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.

Your letter to the bugman:  Hi,
I was walking along the Fighting Creek Nature Trail near the Sugarlands Visitor Center outside of Gatlinburg, TN when I saw this bug. I’ve tried googling it but can’t seem to find a match. Any idea what it is?
Thanks!

One Spotted Tiger Beetle:  Apterodela unipunctata

Dear Matt,
This is a predatory Tiger Beetle, and many species have metallic green coloration, so we decided to search BugGuide for a Black Tiger Beetle and quickly identified it as
Cicindelidia punctulata thanks to this BugGuide image.  According to BugGuide:  “Overwinters as larva, adults present in summer. One- or two-year life cycle” which makes your January sighting quite unusual.  BugGuide data lists April sightings in Florida as the earliest sightings of the year, and most other states only report sightings from May to October.  Perhaps you took this image last summer?

Daniel,
Wow! Awesome – thank you so much!
And yes, you’re absolutely right it was taken last summer (late June)
Thanks again!
Best,
Matt

This is actually a very interesting tiger beetle, Apterodela unipunctata, and a good find. They are most active in late May, through June, into July, and prefer sandy woods. They seem to be mostly nocturnal, and less active in the day, and frequently “play dead” when disturbed. They resemble fast, black spiders as they run through the forest litter, and will hide under leaves.

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.

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.”

Six Spotted Tiger Beetle

Dear BettyLou,
This is a harmless, beneficial, predatory Tiger Beetle, most likely an unspotted Six Spotted Tiger Beetle,
Cicindela sexguttata, which is pictured on BugGuide. where you will find this comment:  “C. sexguttata generally become less spotted as one goes west, so many individuals in Iowa are likely spotless.”

A neighbor of mine posted something about this bug. None of us knows what it is and I was wondering if you knew? I tried to google it but no luck….

Virginia Metallic Tiger Beetle

Dear Penny,
We began our research on identifying this Tiger Beetle with a web search that led us to the Beetles in the Bush site, where there are images of the Florida Metallic Tiger Beetle posted, and they look so similar to the individual in your images, that we suspected they might be in the same genus, so we searched the genus 
Tetracha on BugGuide which led us to the Virginia Metallic Tiger Beetle, Tetracha virginica, which is featured in some nice BugGuide images.  According to BugGuide:  “Crepuscular or nocturnal. Hides during day under stones, rocks, etc., especially near water. Attracted to lights at night” and it is described as “Tiger beetle shape. Glossy green body and elytra, distinctive compared to Cicindela species. Legs are a contrasting tan. Elytra lack maculations. Compared to other members of this genus, no light crescent-shaped markings at apex (tip) of elytra. Note also large size–largest North American member of this genus.”  Tiger Beetles are fierce hunters that pose no threat to humans, and for that reason, we are tagging this entry as Unnecessary Carnage.  We hope you inform your neighbor that these beautiful beetles, much prized by collectors for their gorgeous metallic colors, are beneficial in the hope that future encounters to not end with a death.  As an aside, though named the Virginia Metallic Tiger Beetle, this species is actually reported as far west as Texas and Oklahoma based on BugGuide data.
