Hi! I found this bug on the forest floor. Consulted my Bland identification book but can’t determine what it is!

Caterpillar Hunter Larva

Hi David,
This is the larva of one of the Caterpillar Hunters in the genus
Calosoma.  The adults are large active Ground Beetles that often have metallic coloration.  Both larvae and adults are ravenous feeders that consume caterpillars.  We would much rather see living specimens than preserved specimens in bottles.

Thank you Daniel, I will try my best to snap pictures before preserving or pinning them next time.

Thanks David,
We realized your specimen was for a collection.  Our real issue is with people who squash everything they see and then send us photos of mangled corpses for identification.
