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

And here is the US map for last week:

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

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

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.

Not surprisingly, given how early in the year it still is, there weren’t very many swarms reported last week:

USA:

Daytona Beach, FL
Lakeland, FL

And here is the US map:

 

3.29.15 to 4.4.15

I am not used to getting US reports this early in the year, so it’s exciting to see something different!  I hope I will keep getting reports of dragonflies over the next few months, though this little flurry of activity may stop before the main season resumes in June as usual.  Regardless, this is a great way to start the season and I can’t wait to see what else happens this year!

Well, it’s that time of year again!  Swarms have already started popping up in the US, even though it’s still pretty early to have them.  Here’s the swarms that have been reported since the beginning of the year:

USA:

San Diego, CA
Boynton Beach, FL
Brandon, FL
Fort Lauderdale, FL

Brazil:

Florianopolis, Santa Catarina

South Africa:

Secunda, Mpumalanga

And here is the US map for the first three months of 2015:

1.1.15 to 3.28.15

Though there haven’t been a huge number of swarms reported yet, there was a little flurry of activity this week in Florida with two static swarms and one migratory swarm reported.  I also heard about another Florida swarm on Facebook.  The migratory swarm in San Diego was exciting (at least if you’re me!) as it’s fairly unusual to get those sorts of mass migrations in the western US outside of the variegated meadowhawk migration in Washington and Oregon each fall.  I was very excited about the reports from Brazil and South Africa as they add two new countries to the list of countries where swarms have been reported and bring the total up close to 30 now.  All in all, 2015 is already shaping up to be an interesting year!

I have started seeing a few green darners in North Carolina so far, but nothing else yet.  Here’s hoping there will be a lot more dragonflies out and about soon!

Swarm Sunday: 11/9/14 – 11/22/14

Just a few swarms to report from the last few weeks:

USA:

Tracy, CA

Spain:

Estepona

And here is the US map for the last two weeks:

Swarm map 11.8.14 to 11.22.14

Only 2 swarms in two weeks, but both were migratory, including one international sighting in Spain.  At this point I’ll be surprised if we see any more swarming in the northern hemisphere before the end of the year, but please do report swarms if you see them!  Any northern swarms from here through March will be very exciting.

The swarming activity is going way down as the weather begins to cool, but swarm reports came in from the following locations over the past few weeks:

USA:

Shadow Hills, CA
Piscataway, NJ
Manhatten, KS

Argentina:

Mar Del Plata

And here is the US map for the last two weeks:

 

2014 10 27 to 11 8

Only 4 swarms in two weeks, so the swarming activity is clearly slowing down.  It is getting cooler in many parts of the country and the abundance of dragonflies is going down with it.  But, there are still a few dragonflies out there!  The two American static swarms took place fairly far north, and there was even one migratory swarm in California.  These swarms are quite late in the year (four weeks late!) and I wouldn’t be surprised if we get just a few more.  That’s super cool!

So keep looking for a few weeks more and report any swarms you see!  Would love to have a swarm report from the middle of November, just to see if it’s possible.
