Your letter to the bugman:  Hi! This handsome fella was crawling around on the sidewalk in my neighborhood the other morning and I’d love to know what it is. He kind of looks like a cross between a centipede and a beetle. Thank you for sharing your love of our wriggling insect friends!

“Handsome” Ground Beetle Larva

Dear E in Madison,
Thanks for your kind words and thanks for using the word “handsome” to describe this Ground Beetle larva.  Just last week Daniel dug up a similar Ground Beetle larva and he posted an image to What’s That Bug?

Hi Daniel,
Ahhhh that makes sense! Thank you very much for your reply, and apologies for missing the previous photo from last week.
Bugs are beautiful! Thank you for taking the time to share your knowledge and enthusiasm.

Gentle Readers,
Yesterday while digging in the garden where he made a compost pile in April, Daniel encountered the predatory beetle larva, almost two inches long, and he moved it to another place in the garden where no new activity is planned.  Research on BugGuide indicates this is a Ground Beetle larva.

Ocellated Tiger Beetle

This harmless, predatory Tiger Beetle did not kill your tree.  We believe we have correctly identified it as an Ocellated Tiger Beetle thanks to this Gossamer Tapestry image and this BugGuide image.  We will be tagging this submission as Unnecessary Carnage in an effort to educate the public that every insect encountered is not a threat.

Ground Beetle Larva

Dear Cher Mom,
Immature insects often present greater identification challenges than adult insects present.  We suspected this to be a Ground Beetle larva and we found supporting visual validation on Project Noah which has a similar looking image identified as a Pterostichini sp. and on BugGuide where a similar image is identified as a
Pasimachus species.   Ground Beetles are predators as larvae and adults and Caterpillars are often a preferred prey.

Carolina Metallic Tiger Beetle

This is a beneficial, predatory, Carolina Metallic Tiger Beetle, Tetracha carolina, which we identified on BugGuide and on Flickr.  According to BugGuide, the habitat is “Sandbanks of rivers, pastures, open, disturbed areas; often near water. Hides under boards, rocks, trash, etc. during day” and “Nocturnal. Comes to lights. Apparently, does not fly often.”

Your letter to the bugman:  Saw these tiny little perfect holes in my newly seeded beet bed and carefully excavated with a small twig, maintaining the integrity of the hole; when I got to about 5-6 cm. down this “scary” beast jumped up and attacked the stick! It’s about 1.5 cm long. Could this be what made for an unsuccessful beet bed last year?

Tiger Beetle Larva

Not at all Mary.  This is a beneficial, predatory Tiger Beetle larva.  Here is a BugGuide image for comparison.  

Thank you! So wonderful- I was hoping it was one of the ground beetles! Not being sure, I set it free behind my house far from vegie garden, in my wildflower garden! Now I will know for sure and  will leave them be. This is the first year I haven’t rototilled, hoping to encourage beneficials.
