Making a Kick Net by Hand

Kick nets are great tools for collecting insects in streams.  They consist of a rectangular sheet of netting that’s supported on either side with poles.  They typically require two people to operate, one person who holds the net upright in the water with the bottom edge of the net laying against the streambed and a second person who “kicks” by stirring up all of the substrate with his/her feet.   The insects that are dislodged drift downstream into the net.  Kick nets of varying quality are available commercially and if you want to use a kick net to do research, you’ll be better off buying a well made one that you can use for a long time.  However, if you are collecting for fun, doing educational programs, or simply want to explore a stream, a handmade kick net will do just fine.

There are several ways to make kick nets, including simply stapling screen to a pair of dowels with a staple gun, but I like one that’s just a little more complicated to make.  I find they come apart less easily and don’t require quite such frequent repairs.  To make it, you’ll need the following:

  • Window screen. The kick nets pictured in this tutorial were made from a roll of 36” x 25 foot screen, which you can purchase at a hardware store and will make several nets.  I recommend the 48” screen if your water is more than a foot deep.
  • Two wooden dowels – I use 1/2″ x 36” dowels. If you are working in deeper water, get 48” dowels instead. Any diameter dowel will work, but I recommend something between about 1/2 inch and 3/4 inch.  Anything smaller is easy to break and anything wider is needlessly heavy.
  • Two thumbtacks (optional)
  • Scissors
  • Sewing machine or needle for hand sewing
  • Thread – I recommend nylon thread for longevity

Sewing machin

I have been sewing since I was about 8 years old, so I use a sewing machine to make my nets.  You can do the exact same thing I describe here stitching by hand – it just won’t be as quick to make.

Step 1.  Cut a rectangle of screen.  I cut 2 foot sections from my roll, so my pieces were 36” (the width of the roll) by 24”.  I use the width of the roll of screen as the width of my net, so the length I cut from the roll is the final height of my net.  The nets I make are 34 inches across and 24 inches high when complete.

Step 2.  Fold over about 1” along one of the shorter edges (make it closer to 1 1/2  inches if you’ve got a 3/4 inch dowel).  Pin if needed.  Stitch in place about 1/4 inch from the raw edge.  If using a sewing machine, backstitch at both ends.

Stitching a dowel pocket

Step 3.  Stitch across the tube you made about 1/4 inch from one end.  Stitch back and forth a few times for a strong seam.

Stitching along the bottom

Step 4.  Repeat on the other end of the netting, folding over about 1 inch, sewing 1/4 inch from the raw edge, and stitching across the bottom of the tube.  Make sure the “bottom” on both ends of the net are the same!  The final product should look like this:

Stitched rectangle

Step 5.  Insert dowels into the pockets you made.

Step 6.  If you want to be able to remove the dowels easily when not in use, you’re done.  This makes it easier to fold up and put away.  However, it makes the kick net harder to use as you have to hold the net in place in the stream and also hold the dowels in place in the pockets.  I like to add a couple of thumbtacks to hold the net in place during use.  Press them part way in with your thumb and then hammer them in the rest of the way.

The final net should look like this:

To make your kick net easy to carry, roll the net along one of the dowels and secure in place with a twist tie or other fastener:

It takes me about 15 minutes to make one of these nets with a sewing machine and they cost about $4 altogether.  Considering how much the professional kick nets cost, I much prefer making a new one of these when one breaks than laying out the cash for a new pro net.

Good luck and here’s hoping you find many interesting things with your net!

Smoky Mountain Insects

Oh wow, it’s been a month since I last posted anything.  Whoops!  Can only say that it’s been a REALLY busy month and work with a lot of long hours and evening programs. But things slow down for a little while and that means I have the time and energy to blog!

Last weekend I went to Great Smoky Mountains National Park and helped one of my coworkers lead an educator trek.  At the museum where I work, educator treks are open to formal and informal educators (people who work at museums, zoos, environmental education centers, and the like) and take them out into the field for one to seven days to learn about nature and science firsthand.  For this particular three-day trip, we spent a day at the facility at Purchase Knob learning from the rangers about citizen science efforts that are being done at the park and getting some hands on experience.  It’s a spectacularly beautiful place:

We looked at the status of a bunch of trees for the Nature’s Notebook project and did a leaf litter arthropod study that the park oversees.  The latter involved putting leaf litter into a shaker box, shaking it vigorously, and then using an aspirator (also known as a pooter or, as our ranger calls them, “suckie upper thingies”) to transfer any animals to a vial for examination back in the classroom.  It was fun watching the teachers respond to the insects they caught once they were projected onto a big screen with a video microscope:

In the afternoon, we walked a very long way down a very steep mountain to get to a stream to check for salamanders along some transect lines the park has set up in the area.  I know next to nothing about salamanders, but apparently the pygmy salamanders we saw are very interesting and we saw 7 species altogether.  As the last group finished measuring the salamanders they’d caught and recorded their data, the rest of the group wandered down to the stream to look for more salamanders.  Now I love salamanders, but you all know I’m much more into stream insects than anything with  a backbone.  We found a bunch of flat-headed mayflies clinging to rocks and someone brought over this stonefly:

I think it’s a perlodid stonefly, but honestly I didn’t look at the mouthparts because I was partly in charge of the group.  One of the teachers was looking for salamanders in a little puddle between a big rock and the shore and found one of these:

A roach-like stonefly!!!  I did a little happy stonefly dance and may have yelled a little as I tried to get everyone else excited about it.  Sadly, most of the group was much more interested in the salamanders to care about this amazing stonefly, but it didn’t diminish my excitement over it.  The same teacher found another one too.  I’ve seen specimens, but never a live one, so it was very, very exciting for me.  It’s hard to describe the joy you get from seeing something in the wild that you’ve been hoping to see for a while. It’s a pretty amazing feeling.

After the long trek back up the hill, we went on a wildflower hike.  The Smokies are known for their amazing wildflowers and there were many species in bloom.  We had the group do some nature journaling so they could just sit and look at the flowers for a while. Totally by accident, the trillium that I chose to sketch had insects on it:

Two longhorn beetles that ended up getting frisky as I drew my flower and a teenie, tiny caterpillar was starting to make a tiny hole in the petal when I left.  Insects always improve flowers as far as I’m concerned, even one as awesome as a trillium.

It had apparently been unusually dry in the Smokies for a while, but it rained hard our second night there.  We went to Cataloochee Valley the last day to hike a bit, look for elk, and learn about human impacts in Great Smoky and everything smelled clean and bright.  When we arrived back at the vans, we were treated to a HUGE group of butterflies puddling in the damp dirt:

This photo doesn’t even begin to do justice to the number of swallowtails in the area!  I suspect that because it had been dry for a relatively long time, the butterflies may have been hard up for the salts and minerals that they usually suck out of the soil when they “puddle.”  Dry weather means dry soils and limited puddling opportunities, but the rain seems to have brought the butterflies out in force.  I have never seen so many large butterflies in one place at one time in the wild and they were swirling all around us.  It was amazing!  One of the teachers wandered off a bit and came across this:

That’s a big bunch of butterflies on a big pile of scat, happily sucking nutrients from the wet surface.  If you look closely, you’ll also see a burying beetle.  The butterflies were doing a pretty good job keeping it away from the scat as they fed, so at one point it climbed right over the top of their wings in an unsuccessful attempt to find a place where it could feed also.  The beetle made the whole amazing butterfly experience even better!

Even though I was with a group and didn’t get to spend nearly as much time poking around for insects as I would have if left to myself, the whole trip was just fabulous. The teachers we had with use were amazing and very excited to get out into the mountains and we saw a lot of really excellent wildlife.  The insects were just a happy bonus!  But they make me want to go back and explore more.  Planning another trip there this summer!

Today’s the last day of my Photography 101 course and the final theme is “triumph.”  It just so happens that moments after I read the theme, I managed to get two shots that I’ve been trying to get for 4 years, a clear shot of two beetles that a) either bury themselves in the rocks at the bottom of my tank or b) just don’t stop moving for more than a fraction of a second so there’s no time to focus and get a shot before it moves on.  So, here are my triumph shots, shots that have been a long time coming and very hard-won!  The first is a beetle in the water scavenger genus Berosus (peregrinus, I think):

Water scavenger beetle

Water scavenger beetle

I particularly like this genus.  For one, they’re herbivores, feeding on algae and aquatic plants.  They’re also a very weird shape relative to the other water scavenger beetles. Rather than a long, sleek domed top and a sharp spike on the flattened bottom, these beetle are much more bulbous and round.  I think they’re just adorable.  Their best characteristic though, in my opinion, is the sound they make.  They have a delightful squeak, loud enough to be noticeable without being overbearing, and swim about very quickly while making the sound.  I love that little squeak!  In fact, I can tell immediately when I have scooped one out of the water, no matter how much vegetation and other critters I pull out with them, based entirely on their sound.

This little beetle has become the bane of my existence:

Crawling water beetle

Crawling water beetle

That’s a crawling water beetle in the genus Peltodytes.  They seem to bury themselves in the rocks, dash up to the surface periodically with lightning speed, and then zip back down into the rocks.  SO hard to photograph!  But I happened to look into my tank and it was sitting on one of the little pieces of wood in my tank above the water line.  And it just sat there!  I was able to get about 6 shots before my movement, the flash, or both scared it back into the water, but I got some decent shots of this stupid little beetle after several years of trying.  I was thrilled!  Pumped my fist in the air and grinned like an idiot once it disappeared back down into the rocks.  A triumph for sure!

So, TWO major aquatic beetle photography accomplishments in one day!  I am so excited to have gotten these.  I’ll keep trying to get even better shots, but I consider this a good day’s photography for sure.

Now that my class is over, I’m definitely not going to be posting everyday anymore. This pace is one I just can’t keep up with!  However, I’m going to try to get back into my 3 or 4 posts a week habit and keep that going for a while.  We’ll see how long I can keep that up, but I’m feeling good about the little jump-start this class provided.  Just what I needed to get back into the blogging habit!

Today is the next to last day of my Photography 101 course, and the theme is “double.” Because I’ve been excited about photographing aquatic insects recently, I’ve got another photo from my aquatic setup for you:

lestid gills

Those are gills of a juvenile southern spreadwing damselfly.  A lot of people don’t know that dragonflies and damselflies actually spend most of their lives underwater as nymphs.  In fact, some dragonflies spend up to three years as nymphs, and then 4-5 weeks as adults on land.

As nymphs, damselflies get everything they need from their aquatic habitat, a pond in this case.  They eat small animals as prey, use cattails and other vegetation as shelter, and they get the oxygen they need from dissolved oxygen in the water.  The gills of damselflies help them breathe by improving their ability to absorb oxygen through their exoskeletons.  The gills massively expand the surface area of their exoskeleton, essentially adding another quarter or third of an exoskeleton to their bodies through which they can breathe.  The gills also improve their swimming, the way wearing flippers while snorkeling can help people swim.

However, damselflies lose gills all the time too.  The one in the photo above only had two of the three it should have when I saw it in the water.  Damselfly nymphs will sometimes fight each other and lose a gills.  Sometimes a predator will try to eat a nymph and get a mouthful of loose gills while the damselfly swims away.  While the gills do improve the lives of the damselflies and one missing its gills has a harder time getting oxygen or avoiding predators, they can survive with no gills at all.

I love the way damselfly gills look!  Another fascinating textured surface, compliments of insects.

The theme for Photography 101 today is “edge,” which immediately made me think of the under surface of the water and the aquatic insects that must visit the surface to breathe.  So, I give you a backswimmer getting air:

Notonectid at surface

Backswimmers swim upside down and carry an air bubble with them underwater that they use to breathe (think scuba tank).  Most of their body is coated with a thin film of air as well, which you can see as the shiny, silvery spots in the photo.  All that air they carry with them only lasts so long, however, so they have to go to the surface now and again to get more.  They break through the surface with their butts and allow air to fill their storage space.  Sometimes they’ll sit at the surface for a little while, but most of the time they’ll dart back underwater where birds and other predators have a harder time getting to them.

I love the look of the water’s surface when photographing things underwater.  My kind of edge for sure!

I promised pond insects yesterday, so pond insects you shall receive!  The theme for my Photography 101 course for the day is “glass” and that’s perfect for the type of aquatic insect photography I do.  If you want to photograph things in water, there are a few ways to do it.  You can put the subject in a small, shallow bowl and shoot it from above, but then you miss out on a lot of fun angles and interesting behavior shots.  You can get a waterproof camera, but none of them are nearly as good at macro work as I need them to be for the sorts of shots I’m after.  My way is one I learned from an awesome photographer, Steve Maxson, at an insect photography workshop in 2011. It’s more or less the same technique used by a lot of the people you’ll see posting photos of aquatic insects online.  Basically, you fill a transparent vessel (I use a small aquarium) with water, place your subjects in the tank, and you shoot the photos through the side of the tank with whatever camera you favor.  It’s a great method and lets you get some great shots using the equipment you already have, no special waterproof housing required!

So, here are a few new shots of aquatic insects underwater using my 2.5 gallon aquarium setup and shooting with my Canon 7D and MP-E 65 lens through the glass. All of these are predators, so they’re among the meat eaters in the pond.  First up, a couple of predaceous diving beetles, a small one…

Predacious diving beetle

Predacious diving beetle (I am tentatively IDing this one as Laccophilus fasciatus)

… and a larger one:

Predacious diving beetle (Agabus disintegratus, I think)

And these are true bugs, a giant water bug…

Giant water bug

Giant water bug (Belostoma flumineum)

… and a creeping water bug:

Creeping water bug (Pelocoris sp., likely femoratus)

The beetles have chewing mouthparts, so they eat smallish things that they can chew up quickly.  They eat a lot of insects, aquatic worms, and other invertebrates, though every now and again you’ll see a bunch of them pile onto something like a sickly or injured fish that’s not strong enough to get away.  The bugs have piercing-sucking mouthparts, so they cannot chew their food.  Instead, they grab their prey, jab it with a hypodermic needle-like mouthpart, and inject paralytic chemicals and digestive enzymes.  The chemicals both paralyze the prey and liquefy its tissues.  Once the tissues are nice and soupy, the bug will suck up the juices through its mouthpart like a straw. Essentially, true bugs are digesting their food outside of their body, which they need the paralytic to accomplish.  It takes a LONG time for a true bug to eat anything! However, the paralytic also allows them to eat much larger food, like larger insects, small tadpoles, and fish.  It also gives their bite a little extra punch, should you accidentally step on one or grab one without realizing it.

Photographing aquatic insects is totally my happy place – and I hope some of you will give it a try.  It’s amazing what you can learn by simply following an insect around a tank with a camera for a few days!

Treasure – Close Up!

Today’s Photography 101 theme: “treasure” and close-ups.  I was going to post some very close up photos of insects I found in the pond yesterday, my favorite “treasures” to go hunting for, but I got distracted.  I went to set up my tank this morning so I could start taking photos of them when I noticed that the damselfly from yesterday had just molted, moments before!  So, my “treasure” photos aren’t insects from the pond as planned.  Instead, they represent a treasured moment, the sort of serendipitous moments I come across now and then when I get to see and photograph something ephemeral and special.  This damselfly, an ebony jewelwing, had been free from its old exoskeleton for just a few minutes and was still in the process of stretching out and hardening the new exoskeleton:

Ebony jewelwing , freshly molted

And an inch away, lying limp, was its old exoskeleton:

Ebony jewelwing exuvia

Shed exoskeleton

For those of you who are new to my blog, those little white strings are part of the respiratory system of the previous stage.  When insects molt, they shed their entire exoskeleton, which includes part of their digestive, reproductive, and respiratory tracts.  Those white bits were pulled out of the little series of tubes that insects use to breathe and the freshly molted nymph walked away with a brand new respiratory lining.

As often as I take photos of aquatic insects, I rarely get to see them molt, so I was thrilled I got to see at least part of this shed!  Apparently something went wrong as this damselfly was building its new exoskeleton though.  It only had two of three gills when I scooped it out of the stream. After it molted, it was down to one, but I got to see the gill stretch out and reach its full length, then start to change from the pale cream you see in the photo above to its more typical brown.  So much fun!

It’s always great to get to see something a little out of the ordinary like this!  And tomorrow, I’ll have pond insects for sure.  :)
