Odonata Season
I saw my first living dragonfly outside my windows on Saturday. I’d seen a couple of Common Green Darners here and there during the last few weeks, but spotting an unidentified dragon over 6th Avenue was the real start of the summer flying season for me. On the same day around Green-Wood’s Sylvan Water, I…

Weekend Update
It’s been absurdly warm. Lots of trees are nowhere ready to shake off their leaves. Bumblebees, which can take 60 degree temperatures, you might expect to still be around, but some of the smaller bees were out and about, too. This metallic green bee of the Agapostemon genus, for instance. But it’s late October: there…

Familiar Bluet
Enallagma civile, the last damselfly of the year? This picture was taken on 9/24.This one on 10/6: tandem flight and egg-laying in Green-Wood’s Sylvan Water. I assume the larvae will overwinter.

Scandonata
So they have the same meadow hawk problem over there. These Sympetrum dragonflies are hard to ID in camera. Looks like S. vulgatum or S. striolatum are the options. Found around the moat of the Kastellet in Copenhagen, where the word for them is Hedelibel, or darter. The following mating damselflies were spotted in the…

Darners
The mosaic darners of the genus Aeshna are some of our largest dragonflies. There are 20 similar looking species in North America, so they can be a bear to identify. This looks like a Shadow Darner (Aeshna umbrosa), photographed recently in Westchester Co. They run about 2.9″ long. Shadow Darners can be seen well into…

Spreadwings
I have not come across any of the spreadwing damselflies in Brooklyn. These Lestidae family insects are the exception to the rule that damselflies rest with their wings folded back above their abdomen, in contrast to the dragonflies who don’t fold their wings at all. This year I caught a glimpse of a spreadwing —…

Wing Bands
The Black Saddlebags (Tramea lacerata) is a dragonfly rarely seen perched. But sometimes you get lucky.The “saddlebags” = the dark coloration of the hind wings. This could be an immature male or a female. The yellow spots on the abdomen are the ambiguous tell: a mature male won’t have these.A closer look to examine the…

Dragons/Damsels
Remember the Sympetrums? Devilishly confusing meadowhawks. This a female; possibly a Ruby or Cherry-faced.The Variable Dancer (Argia fumipennis) male is uniquely patterned with purple and blue. They are also called Violet Dancers.A male has a female in tandem flight position, either pre- or post-mating. This is another species I’m seeing for the first time this…

Red Meadowhawks
Obelisking meadowhawk of the Sympetrum genus. This abdomen-up position minimizes the amount of heat hitting the body.The Sympetrum are difficult to distinguish out-of-hand in the field. This could be the White-faced, Cherry-faced, or Ruby-Faced.This male was the only specimen seen at NYBG. The females are even harder to distinguish, but they all know the drill:…

Ode to the Odonates
An immature female Eastern Forktail (Ischnura verticalis). Several members of of the Ischunura genus have immature females with orange on them, but telltale here: segments 1-3 are mostly orange, and that there’s no orange on segment 9. She will lose this color as she ages: the standard female form is an olive green, although there’s…
