Pond Babies: Dragonflies and Diving Beetles

Two weeks ago I told you I'd fill you in when I found dragonfly nymphs in our pond. I wasn't expecting to be able to give you this update so quickly, but SURPRISE, nature moves fast, people! In the last few weeks, I've found more than 50 dragonfly exuviae (the papery exoskeletons shed between molts) attached to the rocks of the pond. Of course, this prompted me to take out my dip net and look for nymphs in the water.

Here's a picture of one I found:

While I was dipping for the dragonfly nymphs, I found a lot of other macro-invertebrates. The list isn't very long, yet, but includes immature mosquitoes, chironomid midges, mayflies, and predacious diving beetles!

InSEX: Mating's Risqué Business in the Insect World

Last night I hosted an InSEX dinner at an undisclosed and secret location. No, we weren't eating insects (in fact, we had a lovely vegetarian meal). Instead, we were discussing their weird, wonderful, and various reproductive strategies!
