Diving Beetle

Predaceous Diving Beetle

Dear Rich,
This is a Predaceous Diving Beetle in the genus Dytiscus, possibly Dytiscus harrissii that is pictured on BugGuide.  Its range, according to BugGuide, is “transcontinental in Canada, also in the northeastern US and Alaska; most common in the east (in the Great Lakes region), rare in the west.”  Of the entire genus, as this might be a different species, BugGuide notes the habitat is “permanent or temporary freshwater ponds and pools …, plus streams and rivers; usually found on or among aquatic plants” and “adults fly from March to November (varies by species).”  Though this is an aquatic predator, they are capable of flying from pond to pond.
