Hello, my name is Krystina and you all helped identify what was a harmless bug. But I’m back with a new bug me and my friends found in the backyard. Thank you so much for your time and knowledge!

Eyed Elater

Dear Krystina,
We are glad you are returning for a new identification.  This is a harmless Eyed Elater, the largest Click Beetle in North America.  Click Beetles are quite amusing.  Unlike most beetles that struggle if they find themselves on their backs, the Eyed Elater and other Click Beetles can snap their bodies, propelling themselves into the air so that they land on their feet.  What appear to be eyes are actually false eyespots that will potentially frighten away a predator that thinks a tasty morsel is actually a larger threat.  Dr. Kent Hovind’s Blog has a children’s story that explains those interesting aspects of the Eyed Elater.  Because our editorial staff will be away from the office later in the month, we are post-dating your submission to go live while we are on holiday.

Eyed Elater

Dear A. Navarro,
This is an Eyed Elater,
Alaus oculatus, the largest North American Click Beetle.  It is universally believed that the striking “eye spots” are protective markings that fool predators like birds into thinking the beetle is a threat as opposed to a tasty morsel.  According to BugGuide:  “Eggs are laid in soil. Larvae predators of beetle larvae in decaying wood, especially hardwoods. Pupation is in unlined cell underground or in rotting wood.”  If you live near a wooded area with rotting logs, it might explain the spike in the numbers of Eyed Elaters you are encountering.

Fire Beetle

Dear Katie,
Based on some research we did many years ago, we learned that Fire Beetles in the genus
Pyrophorus are sometimes called Cucujos.  What you have mistaken for glowing eyes are in fact just eyespots.  The Fire Beetle’s true eyes do not glow.

This guy is in Middle Tennessee. I was wondering what kind of beetle this is, and are those really its eyes or just markings?

Eyed Elater

Dear DL in TN,
The large eyespots on the thorax of the Eyed Elater have evolved as protective mimicry.  A predator like a bird might be fooled into thinking that a tasty morsel is actually a much larger predator.

Hello bugperson,
In the past week I have found two beautiful insects around our home in Fairbanks Alaska. I have looked through your site and also consulted Dr. Google, but have not yet been able to figure out what they might be. The yellowish metallic beetle is on an apple leaf. It was perhaps a half inch long. …  Thanks for any help you can give me.

Green Click Beetle

Green Click Beetle

Dear bugalaska,
Your second beetle is a Click Beetle in the family Elateridae, and we quickly identified it as a Green Click Beetle,
Nitidolimonius resplendens, thanks to a BugGuide posting where it is described as “The head, pronotum and underside are metallic purple and the elytra and legs are metallic green most of the time, but with a change in the light angle, the elytra edges turn purple. At other angles, the beetle is black, especially the underside, so it’s very hard to photograph.”  According to BugGuide, the habitat is:  “variously-aged coniferous, deciduous, and mixed forests; on poplar (Populus), willow (Salix), or on shrubs; adults often found on the spring growth of conifers along margins of wetlands and drainages; boreomontane forest, prairie and parkland poplar groves; larvae in leaf litter and rotting wood.”

Thank you so much for the identification and got all the additional information!  You provide such a wonderful service to bug fanciers everywhere!

Glowing Click Beetle

Glowing Click Beetle

Dear Ross,
Though there is not much visible in your image beyond the vague outline and the two bright green lights, there is no doubt in our mind that this is a Glowing Click Beetle or Fire Beetle in the genus
Deilelater.  Most of our reports come from Florida, and occasionally from Texas, and recently we have been receiving many comments on old postings, leading us to believe there is a spike in populations of Glowing Click Beetles this year, but your image is the first we have received in many years.
