The Blue Dasher dragonfly (Pachydiplax longipennis) is common around our ponds and lakes, especially if there’s lots of vegetation in the water. The males have a chalky blue abdomen, with black tip. The females have no blue at all. But they do have tell-tale paired yellow streaks along their abdomen.
Dragonflies of this species will often hold their wings downward as in this example.

I think he put his wings on inside out this morning.
We brought pond water from Mohonk a couple weeks back that included a slimy mass of eggs — we think they’re dragonfly eggs. How to tell??
Also, this month’s issue of Audubon has a great gallery of photos:

Not so good on pond egg ID, I’m afraid. Frogs by any chance?
No….not frogs, though that’s what we were hoping for, but hatchings do look like dragonflies….they jet around in the water backwards….
