This group of seventh graders had a great day for insect dipping. First we sampled at the outlet, where rushing water and rocking rocks made dipping a challenge. Mostly we had to turn over rocks to find the critters.
Stonefly nymph cases abounded - they were on every rock and all over the grasses along the shoreline! Here is a close-up shot of one; note the crack in the back, from which the adult (see below) emerged.
Some of the kids were really into it, while others preferred the view from the shore.
After a leisurely lunch on the bridge,
we moved to the Frog Pond. What a difference: still water, lots of emergent vegetation. Frogs galore, one tadpole, and many minnows.
This scarey-looking thing is a giant diving beetle (water tiger) larva - the mouthparts are impressive:
These guys were communing on the cattails:
All in all, it was a successful outing. Chaulk another one up for insects!
