Backyard bug profile: Celithemis eponina

Celithemis eponina, Halloween Pennant, close-up. Boca Raton, FL, May 24, 2013.

The beginning of spring, by which I mean the arrival of the rainy season, is one of my favorite times of year here in south Florida. The damselflies and dragonflies are out in significant numbers again, dotting the grasses and trees searching for food. Earlier this week there were dozens of dragonflies cruising the back [...] [...]

After the rains, the odonates appear

Everglades Sprite (Nehalennia pallildula). Boca Raton, FL, May 4, 2013.

South Florida is typically described as having two seasons: wet (May through October) and dry (November through April). Hydrologists like to split this up a bit further, with the wet season (now called high rainfall, low evapotranspiration season) running June through October, and the dry season now divided into two subseasons: low rainfall, low evapotranspiration [...] [...]

Cold spells=insect close-ups

libellula_sp_20121108_0

The first few days of fall in Florida often bring cold (well, cool) fronts to the region. This year we’re already on our second or third round of long-sleeve days, so I thought this might be a good time to show off what I’ve been able to capture of the cold-slowed insect fauna. Here’s a [...] [...]

Dragonfly eyes

blue_dasher_20120603_face

For those who know a few dead languages, it probably comes as no surprise that dragonflies have excellent vision. The very word dragon (via Latin draco, from the Greek δρακοιν) means “to see clearly.” And, as the late Philip Corbet noted in his magnum opus, “no other insects have compound eyes that are larger or contain more ommatidia [facets]. [...] [...]

Dragonflies in 3D

OdonataLogo

If you are At All into dragonflies, you should check out the 3D image library at odonatacentral.org. Absolutely amazing. I became a member several years ago and have checked in from time to time since then. I plan on visiting more frequently now. [...]

New backyard bug: Anax junius, Common Green Darner

anax_junius_oblique_20120213

A couple of years ago I was going through my photo files and ran across a picture of a pretty dragonfly, Anax junius, the common green darner. I had seen this darner on the trail at Fern Forest, and since I was posting about dragonflies at the time, I wrote a brief piece about it. [...] [...]

Dragonfly week comes to a close

Wow, my first-ever Dragonfly Week is already drawing to a close, and I have so many more things I was going to write about! I had planned to at least mention some of the adaptations that go into the incredible aerial feats performed by these “primitive” insects, like their offset thorax, their wings (structurally, they [...] [...]

Another darner from a couple of years ago

Going through my old photo files has been fun for me; last night I found a slightly better photo of Coryphaeschna ingens, the Regal Darner [UPDATE:Gynacantha nervosa, Twilight Darner] who visited us during Tropical Storm Fay. I also ran across a couple of untagged photos of other species that I knew I’d seen, but couldn’t [...] [...]

Dragonfly species of Palm Beach County

My post about the Pierides the other day got me thinking of Alexander Pope’s advice, in his Essay on Criticism: “A little learning is a dang’rous thing; Drink deep, or taste not the Pierian spring.” Pieria was a region in ancient Macedonia, rather than Thessaly where Pierus and his daughters (the Pierides) lived. But Macedonia was [...] [...]

Backyard animals in June

There aren’t a ton of animals visible in the steamy sunny heat of late June here in Boca; those few that there are, apart from the omnipresent mockingbird and his counterpart in red, the cardinal, tend to be insects. Here’s a blue dasher dragonfly that seems to favor a perch on the spicewood tree on [...] [...]
