Field Notes
We went outside to Mill Stream. There were multiple little bugs on the top of the water swimming around super fast. We used a kicknet, a net, and our super ninja skills to collect the beetles on the top of the water. I had trouble getting a bug because of how fast they were. We caught 4 or 5 of the bugs in the net and then catching the beetles in a vial that I brought down to the stream. We caught twodifferent kinds of inscets, a dopsomfly larvae and a whirligig beetle.

Whirligig beetles have two long legs in the front of their body. This beetle has two long front legs, just like the Whirligig beetle.
Photo of my evidence.
The Whirligig beetle has a smooth outer layer that is metallic. Although the Water Penny also has a smooth, metallic outer layer, the Whirligig has a oval shape unlike the Water Penny.
