Punk Rocker Dragonfly (Well-Nigh Wordless Wednesday)

Check out the “hairdo” on this massive common green darner nymph:

A coworker of mine found it during a pond program last week and I was thrilled to have a chance to bring it home to photograph.  It’s HUGE and really rocking that green hair – what’s not to love?

Bugs at Sunset (Well-Nigh Wordless Wednesday)

My favorite holly tree at work bloomed late last week! This one tree is loaded with insects throughout its bloom and I absolutely love exploring it and looking for insects lurking among the leaves. Once you notice one, you’ll see the most amazing variety of insects roaming about in the tree!  Some things are small and hidden, and others are right out in the open where they’re easy to spot, such as this leaf-footed bug:

Leaf footed bug

I believe this is an eastern leaf-footed bug, Leptoglossus phyllopus

I like the way the setting sun turned this normally somewhat drab insect such beautiful colors.  I’m looking forward to exploring the tree more this year and seeing what other treasures I can find!

Aquatic Insects and Bioblitzes (Friday 5)

A few weeks ago, I was given a really fun opportunity to be a part of a bioblitz workshop.  Bioblitzes, for those unfamiliar with them, are biodiversity documentation events, often done over a short time period and at a specific facility, to document and/or monitor the species present on the grounds.  Bioblitzes often invite the public to take part as a way to get help collecting and identifying species while also teaching everyone about local natural history.  The workshop was geared toward park and environmental education center staff that are interested in using bioblitzes to make sound management decisions and/or educate the public.  A variety of scientists demonstrated how to collect or otherwise document a range of species, including reptiles and amphibians, small mammals, large mammals, birds, plants, and insects.

Guess which part I taught?  Aquatic insects!  I manged to get about half of the 40 participants actually IN the water to look around for aquatic insects in the urban stream that flows through the park hosting the workshop and we found… not a lot.  The neighborhood adjacent to the stream has an awful drainage system that dumps all the runoff right into the stream without any sort of filtration, so the stream floods often.  Still, we found some interesting things!  They included this:

Net spinning caddisfly larva

Net spinning caddisfly larva (Hydropsychidae)

That’s a type of net-spinning caddisfly!  They build little silken nets across rocks in swiftly flowing areas of streams to catch food, then hook themselves into the nets.  While caddisflies in general are considered good indicators of water quality, this particular group is capable of reaching HUGE population sizes in some quite heavily disturbed areas.  Still, always fun to find caddisflies.  We also found some adults:

Net spinning caddisfly

Net-spinning caddisfly adult

This little guy was hanging out on a blacklighting sheet, presumably in the same spot it had sat the night before.  Caddisfly adults look a lot like moths, but instead of having scales on their wings they have hairs.  Their order name, Trichoptera, means hairy wing, so it’s easy to remember this distinguishing characteristic if you know your roots.

We also found these lovely larvae in the stream:

Crane fly larva

Crane fly larva

Crane flies!!  They’re huge and squishy and ooze all over when you catch them, so they’re really quite gross.  Many have gnarly looking fleshy bits on the back end that they use to breathe (which naturally makes them exciting to me!) and some have a sort of ribbed appearance like this one.  Unlike a lot of fly larvae, they actually have a complete, hardened head, but they keep it retracted inside their bodies.  I enjoy finding these larvae and they’re really fun to show off to people when you find them in a stream.  That huge monster ends up turning into something like this:

Crane fly

Crane fly

I know I’ve said it before and I’ll say it again: crane flies are harmless to people!  A lot of people are scared of them and many think they bite, but they do not.  They’re also not giant mosquitoes – completely different groups!  I think they are really beautiful.

I’m going to wrap up with this

Common baskettail

Common baskettail

There weren’t a lot of dragonflies out during the workshop as the dragonflies were really just starting to come out, but one of the reptile and amphibian guys found this dragonfly on the ground.  It was still alive, but clearly had some issues when it emerged as an adult and I doubt its wings worked.  Granted, I have seen some butterflies flying with as little as a wing and a half, so who knows?  Maybe this little dragonfly is still zipping around the pond, hunting insects and having a great adult life!

Even though I’ve participated in enough bioblitzes and done field work with enough scientists that I didn’t learn many new things about how to sample for a variety of organisms, I still had a great time at the workshop!  The people who attended were really excited about it all, so it was a lovely, energetic group.  I also got to see a white-footed mouse, a great horned owl, several turtles and frogs (including a new-to-the-park’s-species-list river cooter), a new-to-me dragonfly species, and a variety of insects.  Plus, I got to spend an afternoon in a stream teaching people about aquatics!  It’s hard to beat a day spent with other nature geeks.  Hope I get to do it again soon!

Butterfly Taunts (Well-Nigh Wordless Wednesday)

I found myself in California for the second time in two months for a friend’s wedding last weekend. A group of us went on a hike at a little roadside attraction and saw a bunch of these butterflies:

California sister

California sister, Adelpha californica (I think…)

They kept darting away right as I hit the shutter release so I ended up with dozens of photos of random grasses with no butterflies.  Fun times with insect photography!  I got this one on something like the 50th try.  Good timing too.  Was about ready to throw my camera at one of them out of sheer frustration…  :)

Blacklighting (Well-Nigh Wordless Wednesday)

Know what makes for a good Wednesday evening?  This:

Blacklighting

Blacklighting

First “blacklighting” night of the year!  (I’m using the quotes because we only had a mercury vapor light and no blacklights.) A bunch of my coworkers and several interns got together to see what comes to Prairie Ridge and it was a blast, right up until a nasty storm blew in and we all had to scatter.  Here’s to many more blacklighting adventures this year!

First Dragonflies and Damselflies of 2015 (Friday 5)

I’ve been looking forward to starting dragonfly programs at work again this year, so I’ve been trekking down to the pond occasionally to check on the dragonfly situation there.  I saw my first common green darner on March 24, which is pretty early.  When I went to check up on them yesterday, I saw 5 species!!  And you know what that means: it’s time for Friday 5!  Here’s what I saw:

Common Green Darner

darner in cattails

Now this photo is truly terrible, but I couldn’t get my camera to respond as quickly as I’d like.  I challenge you to find the dragonfly in this photo at all!  However, there IS a common green darner in the photo, and it was one of six at the pond.  I saw two pairs mating, so 4 males and two females.  I suspect these are migrant green darners.  The nymphs in the pond are all still too small to be emerging and it’s been too cold for too long for me to expect them to be coming from our pond this early.  Between that and the fact that I’ve been hearing reports of big migratory and static darner swarms in Florida, I think that these are green darners stopping over on their way north for the summer.

Blue Corporal

blue corporal

 

These dragonflies come out very early relative to other dragonflies and I tend to see very, very young individuals on the rare occasions that I see them at all.  This is a photo from last year as the photo I took yesterday didn’t turn out at all, but it was nearly identical in appearance.  I find these when they fly, almost drunkenly, from an area near the pond to the grassy hill beside the pond and crash into the grass.  For whatever reason, nearly every blue corporal I’ve ever seen has been freshly emerged and its wings have hardened just enough for it to fly badly a very short distance.  The wings will darken a bit more and become a little less glossy once they finish hardening.  The body will also change colors and the abdomen will expand some as well.  This dragonfly had probably been an adult for an hour, so brand spanking new!

Common Whitetail

This photo is from last year too because I only caught a quick glimpse of a pair of common whitetails in tandem, zooming off over the prairie and they never came back.  I got just enough of a look at them to know that they were whitetails for sure, but definitely didn’t have time to get the camera pointed at them before they disappeared.  These are some of our earliest dragonflies each year, and one of the last to disappear in the fall.  If I had to pick a dragonfly to represent Prairie Ridge, it would be the whitetails as they are far and away the most commonly spotted dragonflies throughout the season.

Fragile Forktail

fragile forktail

This has been the earliest damselfly I’ve seen the last few years, and it was the first I saw this year too.  They are easy to tell from other forktails at the pond by the exclamation mark shaped pattern on the thorax, clearly visible in this photo.  They also tend to be smaller than a lot of the other damselflies you might see flying with them, though this one was quite a bit larger than the average fragile forktail I’ve encountered.  If you look closely, you’ll see that this one was in the process of eating a small insect when I snapped this photo.

Unknown Damselfly

No photo at all for this one!  I saw one blue and black damselfly fly past and then promptly lost sight of it against the grass.  I’d bet it was an Enallagma species of some sort, knowing what we have on the grounds and the coloration of the insect, but who knows which one.  Definitely didn’t get a good look at this one…

Dragonflies are back out!!  After what was a long and cold winter (at least by North Carolina standards), it’s lovely to see the dragonflies out and about again.  Who else out there is seeing dragonflies?  Anyone want to share the things they’ve seen recently?

Have a great weekend everyone!

Pond Dwellers (Friday Five)

I’ve been spending a lot of time photographing aquatic insects recently.  I’ve been very busy at work, so I find it relaxing to sit and watch my little tank full of insects in the evenings, observing their behaviors and photographing them.  Next week I’ll share another developmental series like the snail series I posted last week, but in the interest of time as the day is almost over, today I’m going to simply share some photos that I’ve been taking.  Here are some of my favorites this week:

Backswimmer

Notonecta

Backswimmer, Notonecta sp. (likely indica)

I’ve had these guys in the tank for a couple of weeks now and they are really fun to watch!  They have all sorts of cool behaviors and they’re absolutely stunning.  I’ve been trying to track down exactly which species these are and I think they’re Notonecta indica, but I really need to get a species key and run them through to be sure. In the meantime, I just enjoy watching them and admiring their gorgeous eyes and the pearlescent blue-white patch on their foreheads.

Creeping Water Bug Nymph

Ambrysus

Creeping water bug, Pelocoris sp.

This particular creeping water bug lives up to its common name in more ways than one.  Not only does it creep along the rocks and the pieces of wood in the tank, but it also peers out at you from hidden nooks and crannies in the tank.  It’s watching you, even if you don’t see it – it’s a creeper!  They’re quite beautiful creatures though, and he crawled out of his hiding spot just long enough for me to get this shot before he dove back under the log.

Damselfly Nymph

Ischnura

Damselfly nymph

This isn’t the best photo ever as I had accidentally dialed my aperture WAY down without noticing and the depth of field isn’t that great.  However, you can see a lot of cool structures inside this damselfly, and that’s why I like the shot.  Judging from their prominent connection to the tracheae (= air tubes that transport oxygen throughout an insect’s body) in the gills, I suspect those brown squiggly lines are large respiratory organs that bring oxygen from the gills to the head.  Pretty darned cool!  (At least it is if you’re me!)

Mayfly

Batidae

Mayfly nymph, family Baetidae

I have very few photos of mayflies in my collection and it’s due in large part to their fragility.  They get eaten by everything (indeed, this particular individual was snagged by a backswimmer just a few minutes after I got this shot) and they do not transport well at all.  Sloshing around in a container of water is really hard on them and they rarely make the trip.  I was thrilled that this one was still alive when I got it home so I could get some photos of it, though it was missing a couple of legs on this side.  I still really want a good, closeup shot of a mayfly’s gills.  They’re really interesting!  That’s going on my photographic bucket list.

Water Strider

Gerris

Water strider, Gerris sp.

This is technically not a true aquatic insect as it lives on the surface of the water and not in the water, but who can resist a good water strider?  These suckers are hard to catch thanks to their amazing vision, and I managed to catch TWO of them at once!  Granted, they were mating, so they may have been otherwise occupied and perhaps paying a little less attention to their surroundings than usual?  I think these are gorgeous animals, well worth the effort of chasing them down in the pond and then again with the camera as they skip frantically around the tank…  It’s always a treat when they slow down long enough for you to get a shot!

And with that, I’m off to sleep.  Lots to do at work tomorrow!
