Predaceous Diving Beetle

Dear M,
This is a Predaceous Diving Beetle in the family Dytiscidae, probably in the genus Dytiscus, and possibly Dytiscus fasciventris which is pictured on BugGuide and described as:  “only the anterior and lateral margins of pronotum are bordered by a broad pale stripe (posterior margin not bordered); lateral margin of elytron bordered by broad pale stripe on basal half only remainder of dorsal surface brown, brownish-black, or green; ventral surface yellow to reddish except metacoxa yellow and metasternum brownish-black medially.” Though they are aquatic, Predaceous Diving Beetles can fly from pond to pond and they are sometimes attracted to lights.

Awesome response time haha! Thank you so much!

Our timing aligned.
