Water Pennies

Scientific Name
MatchScientific Name

This common name refers to only one family.

Beetle Family Psephenidae

These are pretty much always called Water Pennies.
These interesting insects are not mentioned in trout fishing literature, but they turn up once in a while in my Eastern samples and I understand they are also common in the Midwest.
