Not many migratory events have been reported yet, but I think that’s coming soon, sometime in the next week or two.  The activity over the past few weeks is the sort of conditions we normally see right before the migration of the common green darners – lots of reports from the Great Lakes region, a few in Nebraska (that’s always a good indicator for some reason!), and dragonflies massing in New England.  Next week or the week after, I’d expect those masses to start shifting southward so that we’ll see a lot more activity in Virginia, the Carolinas, Missouri, and Arkansas as the dragonflies start following the eastern coast and the midwestern rivers toward the Gulf of Mexico.

No indication that the western migration has begun at all yet!  I start looking for reports of dragonflies swarming in Montana, Idaho, and southern Canada and you’ll usually see the Washington-Oregon migration of the variegated meadowhawks shortly afterwards.  No sign of anything so far this year though!

All this means that we’re heading into the prime swarming season very soon.  If you see a swarm, please report it.  We can follow the big swarms down the coasts and rivers if people report the swarms they see!

Lots of activity reported from the northeastern US, including the areas around the upper Midwest and New England.  Starting to look a lot more like the migration season is upon us!  Next week I expect to start seeing increased reporting in the mid-Atlantic states and perhaps a few more in Nebraska, Arkansas, and Missouri.

This is the prime season for swarms, so be on the lookout in your area!  If you’re along the east coast or any of the rivers in the Midwest, you’re likely to see swarms over the next few weeks.  Hope you’ll report any you see!

July started off a little slow, with a few swarms reported in the central part of the country along with a cluster in North Carolina.  For whatever reason, there were several swarms reported in drought-ridden  southern California, an area that normally sees very little swarming activity.  Perhaps these are dragonflies about to move to a better area?  The week of July 12th saw a little more activity in the Midwest, with swarms occurring along the Great Lakes, the Illinois River, and the Mississippi River with a smattering of other swarms across the country.  The week of July 19th saw increased activity along the Illinois and Mississippi, but still little along the western coast of Lake Michigan.  A flurry of activity in that area suggests that the migration season is about to begin, and that flurry started last week, the week of July 26.  That coupled with the sightings along the Mississippi and Missouri Rivers and in Arkansas, Oklahoma, and Louisiana suggest that the 2015 Midwest migration may have already begun!  It’s a few weeks earlier than normal, so it will be interesting to see if the dragonflies continue southward over the next few weeks or stay in place for a little while before they start moving at their regular time in mid-August.  The coastal migrations have apparently not yet begun, though I suspect they may start in the next few weeks.

Peak swarm season has begun!  If you see swarms, I’d love to hear from you.  Click on the link below to add your story!

Well, that’s not something you see everyday!  Look how many reports of US dragonfly swarms came from the west!  There is still a lot of action taking place along the Front Range in Colorado, as there was last week, with nearly all contributors reporting severe weather in the area.  There were also reports in Utah, Arizona, and Idaho, all of which rarely see swarms.  The two lone eastern static swarms took place in states bordering the Atlantic and there was a migratory event along the northern edge of Lake Superior recently as well.  Overall, a very odd week, so I can’t wait to see what happens next week!  Will it be another weird week with a lot of western swarms, or will the normal pattern of mostly eastern swarms reassert itself?

We’re heading into the peak season this week or next, so expect to see a larger list of swarms coming soon!

Swarm Sunday: 6/21/15 – 6/27/15

Dragonfly Swarm Project logoIt’s Sunday, so time for this week’s swarm report!  Swarms occurred in the following locations over the past week:

USA:

Mobile, AL
Aurora, CO
Boulder, CO
Broomfield, CO (2 swarms)
Centennial, CO
Denver, CO (3 swarms)
Longmont, CO
St. Charles, MO
Long Branch, NJ
Cayce, SC
Spokane, WA

Vietnam:

Hoi An

Clearly there’s something interesting going on in Colorado!  Everyone is reporting flooding and severe storms there, so it looks like a disturbance in the area is stirring up the dragonfly population pretty well.  That seems to happen periodically in Colorado – big storms or fires or floods produce big dragonfly events for a few weeks.  We’ll see if it lasts into next week.  Otherwise, just a few reports scattered across the country, i.e. the normal conditions for this time of year.  Also, a new country for the list where swarms have been reported to date: Vietnam!  That brings the total up to 31 countries, which really highlights the fact that a variety of species do this behavior and it’s not specific to a certain area or group of species.

The season should be picking up soon, so send in reports of any swarms you see!

Swarm Sunday: 6/14/15 – 6/20/15

Dragonfly Swarm Project logoThis week was a bit slow swarm-wise, but I thought I’d do a report anyway.  Swarms occurred in the following locations over the past week:

USA:

Boulder, CO
Interlochen, MI
Saint Ignace, MI
Willard, UT

And here is the US map for last week:

Swarm map 6.14.15 to 6.20.15

Just 4 swarms this week, so not a very exciting week.  Three of the swarms were near big lakes (including one near the Great Salt Lake) and one was quite far from any major bodies of water.  Hard to draw many conclusions from this week’s data apart from the fact that we’re still clearly in the slow part of the year.

If you see a swarm, the link to the report form is below!  I welcome reports of any and all swarms!

Swarm Sunday: 3/29/2015 – 6/13/15

Dragonfly Swarm Project logo

The swarm activity has been rather slow over the last few months, so I’m combining a lot of dates into one report here rather than reporting just one or two swarms each week.  The following swarms have occurred between the end of May and today:

USA:

Goldstream, AK
Boulder, CO (2 swarms)
Homosassa, FL
Lexington, GA
Crystal Lake, IL
Bossier City, LA
Brownville, ME
Hugo, MN
St. Paul, MN
Spicer, MN
White Bear Township, MN
Bloomfield, MI
Bernardsville, NJ
Morris Plains, NJ
Greenville, NC
Lake Waccamaw, NC
Charleston, SC
Port Aransas, TX
Sheboygan, WI
Waupaca, WI

Thailand:

Sritanu, Ko Phangan

And here is the US map for the last month and a half:

3.30.15 to 6.13.15

Red pins are static swarms, yellow pins are migratory. Click the map to enlarge!

Most of the early activity, as in past years, has been static swarming.  Looks like most of the swarms have taken place near bodies of water so far this year, near large lakes and along coastal areas and largely east of the Mississippi River.  It will be interesting to see if more swarms occur inland once the season really starts to pick up, as has happened in past years, or if everything is different this year.  I suspect we’ll see more swarms inland over the next few months, the usual pattern, but only time will tell.

Now that the swarm season has really begun, I’ll start posting more often.  In the meantime, keep sending in those swarm reports!  Every one matters and helps explain what’s going on just a little more.
