Toebiter

Dear M Grybko,
This is a Toebiter, also known as a Giant Water Bug or Electric Light Bug.  This is one of the most frequent identification requests we receive.

Thank you for the quick response. I haven’t seen one before and I am over 50.

Your letter to the bugman:  This is the biggest beetle I have ever seen in Utah. I would have thought it was a kind of cockroach but we don’t have cockroaches this far north in Utah. I poked it with a big zip tie, to see if it was alive, and it was. The zip tie made the beetle look small in the picture but the zip tie is just really big. The beetle is approximately 2 and 1/8th or 1/4th  inches long. it has two big pinchers, or legs I can’t tell, when it was resting the pincher/legs were in front of it, and when I poked it lifted its self off the ground and held them up as seen here in the picture.

Toebiter

Dear Addy,
This is not a Beetle but it is the largest True Bug in North America, the aquatic Giant Water Bug or Toe-Biter.  They are alleged to have a very painful bite and more than one swimmer has encountered a Toe-Biter while wading, justifying the common name.  Though clumsy on land, they are quite agile while swimming and catching prey like small fish and tadpoles as well as other insects, and when their ponds dry out, they are capable of flying great distances in search of more standing water.

Thank you, that is very helpful.

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.

Water Scavenger Beetle

Dear Ellis,
We believe your aquatic beetle is a Water Scavenger Beetle in the family Hydrophilidae which is well represented on BugGuide.  Many aquatic insects, including Water Scavengers, are able to fly from pond to pond and some species may be attracted to lights.
