Tiger Beetle Larva

Dear The Dude Man,
First off, congratulations on the 20th Anniversary of The Big Lebowski.  Secondly, and probably more importantly, we are thrilled with your awesome images of a Tiger Beetle Larva, which is pictured on BugGuide.  According to the University of Nebraska-Lincoln Department of Entomology website:  “The newly-hatched larva enlarges the hole and burrows perpendicularly to the soil surface. This is accomplished byloosening the soil with its mandibles and using its head and thorax like a shovel to carry the soil. At the surface, the larva flips the soil backward off its head. There are three larval stages, and larvae enlarge and lengthen their burrow as they grow. The burrow may be 18 inches or more in depth, depending on the substrate. While in their burrows, larvae can survive without food for weeks and can also survive temporary flooding. They do not leave their burrow under normal circumstances but often wait at the burrow entrance to ambush small arthropods. When a suitable victim is near, the larva attacks with lightning speed. It throws its head (usually backward) to grab the prey with its sickle-shaped jaws. Then, it pulls the prey down into the burrow to devour it. Somewhat like a spider, larvae secrete digestive enzymes to help break down their food before ingestion. Tiger beetle larvae are unique in that they have hooks located on the back of their abdomen to anchor them to the side of the burrow while they subdue large prey. Tiger beetle larvae, in turn, are fed on by hister beetles, birds, and ants, and are parasitized by bombyliids (bee flies) and several wasps. The larval period may last up to four years depending on the species.”  We hope you were able to return this Tiger Beetle Larva to its hole.

This is definitely not a Desert Stink Beetle in the genus Eleodes.  It is a beneficial, predatory Ground Beetle in the family Carabidae.  Here is a similar looking individual pictured, but not identified, on BugGuide.

Big Headed Ground Beetle

Dear Grifftuh,
This is a harmless Ground Beetle in the genus
Scarites.  Though the common name of Scarites subterraneus, according to BugGuide, is Big Headed Ground Beetle, the name could apply to the entire genus.

That’s great.  Thank you Daniel.  I appreciate you getting back to me!

Northwest Hairy-Necked Tiger Beetle

Dear Larry,
This is a beneficial, predatory Tiger Beetle in the subfamily Cicindelinae, and based on images posted to The Xerces Society and BugGuide, we believe it is the Northwest Hairy-Necked Tiger Beetle,
Cicindela hirticollis siuslawensis.  According to BugGuide:  “Almost always in close association with a body of water i.e., sandy beaches of streams, rivers, lakes, and oceans.”
