Click Beetle

Hi Andy,
This is definitely a Beetle, but beyond that, we are stumped.  Generally we are able to at least provide a family for beetles, but there are so many physical attributes that are distinctive on this beetle that we have not seen combined in this manner.  The pectinate (see BugGuide) are probably the most distinctive feature, but the spined thorax and narrow waist connecting to the abdomen is also quite unique.  Many beetles in the superfamily Elateroidea (See BugGuide for North American examples) have similar antennae and thoracic features, including some of the Click Beetles in the family Elateridae.  At first glance, we thought this might be a Prionid, but the thorax structure seems to negate that possibility.  We need additional time to research and perhaps one of our readers will be able to assist in this challenging identification.  We could not locate it on ThaiBugs.  Can you recall the size of this creature?

Unknown Beetle from Thailand

Immediate Update:
After posting we looked again at the ThaiBugs site and found a Click Beetle in the family Elateridae that looks close.  It is “unidentified and in need of a shave” and pictured as a thumbnail near the bottom of the page.

Daniel:
Yes, a click beetle!  I believe this one is Oxynopterus mucronatus, or at least something very closely related.  Thanks for sharing!
Eric

Thanks Eric,
We found matching images on Project Noah and the Click Beetles of the Palearctic Region website.

Hi daniel was about an inch long. dificult to gauge the with from memory.But remember being fascinated by the antenae type and size,which was noticably wider than the body.

Green Click Beetle

Hi Clare,
We are relatively confident that we have identified your Click Beetle as a Green Click Beetle,
Nitidolimonius resplendens, based on images posted to BugGuide, which lists the habitat as:  “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.”  The only sightings reported from BugGuide are in Alaska, Alberta Canada and New Hampshire.

WHAT IS THIS?????????

I noticed this on the sidewalk yesterday. It was about 2 inches long. I have never seen anything this big or unique looking – any ideas what it is and where it could have come from?
sorry the picture is a little blurry!

Eyed Elater

Hi Krissy,
Because of its large size, bold coloration, extensive range, and distinctive eyespots, the Eyed Elater is one of our most common summer identification requests.

Rare Bug from NJ

Hello and thanks for taking the time to possibly identify this strange looking bug from the attached pic. We found it yesterday in Woodbine, NJ in a wooded area. It hops around like a cricket.

Eyed Elater

Hi Frank,
If identification requests that we receive are any indication, Eyed Elaters are not rare.  We actually have them tagged as one of our Top 10 identification requests.  Eyed Elaters are Click Beetles, and the hopping you describe is the beetle’s ability to right itself if it finds itself on its back.  It can snap its body and flip in the air, producing an audible clicking sound.  The eyespots on the Eyed Elater are a defense mechanism to frighten large predators like birds who might mistake it for a larger creature than the bite sized morsel it actually is.  We are post dating this letter to go live to our site over the weekend while we are out of the office.

Amazing response time…thanks so much…that was awesome. I will spread the word about your great site!
Regards,
Frank

Curious what bug this is? It has been over 100 degrees here in central Kansas. Just noticed them over the last couple weeks. Thanks

Click Beetle

Hi kansas,
This is a Click Beetle in the family Elateridae, a large family with many similar looking species.  They are called Click Beetles because of their ability to snap their body to right themselves if they wind up on their backs, an action that produces an audible clicking sound.  Click Beetles are harmless, though some species are agricultural pests.  The larvae of Click Beetles are called Wireworms, and there are several species of Click Beetles, collectively called the Corn Wireworm, that damage young corn plants.  This Penn State website and this Purdue University website both have helpful information on the destructive Wireworm species.

Queen something?

Found this crawling across the floor of my kitchen this morning, sort of trundling along dragging its long rear end behind it. About 3” long. Photos taken after it was thoroughly drowned in RAID….

Female Click Beetle

Dear Creeped Out,
While we are not certain of the exact identity of this unfortunate creature, we are relatively certain of two things.  First, it appears to be a beetle in the order Coleoptera, and second, it is probably predatory and drowning it with Raid constitutes Unnecessary Carnage.  We are not certain if this is a larva.  We feel more confident that it is a larviform adult.  Females of some beetles resemble larvae.  This might be a Rove Beetle in the family Staphylinidae, or perhaps it is a female Glowworm in the family Phengodidae, or perhaps it is something we are not considering.  We are going to try to get a second opinion on this creature.

Several of my friends suggested termite queen… so, glad it’s not that, at least. :)
Sorry about the unnecessary carnage. I’ll try to have my husband take some better pictures when he gets home tonight (I left the bug under a plastic cup in case the RAID didn’t actally kill it.  Yes, I’m that squeamish about bugs.)  ;P

Hmmm.  Termite Queen might actually be correct in which case we would retract the Unnecessary Carnage tag.  The antennae don’t seem correct for a Termite.  Again, we are waiting for a second opinion.

Yeah, the head seems kinda pointy.  I’ll get Jeff to photo it with a real camera/lens tonight, that should help.

Daniel:
Ah, that is that wingless female click beetle!  Wait a sec….Euthysanius lautus is the species, looking at Art Evans’ book, A Field Guide to Beetles of California.  Here’s a link:
http://bugguide.net/node/view/27029
Ok, so I am not sure if E. lautus is the only species with a wingless female….
Thanks!
Eric

Ed. Note:
Interestingly, we have posted images of the male of the species both in our archives and on BugGuide.

Yup!  Here’s one that looks very similar:

Thank you!  Relieved it’s not the world’s largest termite. And they’re slow-moving enough that if I see another one I will hopefully have the guts to trap and release rather than nuking from a safe distance.
However, I’m kind of hoping they stay outside to start with…

Female Click Beetle

Please don’t post this link directly on the website, since it isn’t permanent, but we took some better photos last night in case you or the bugguide could use them at all:
Thanks again for your help!
(I don’t suppose you know what the juveniles look like?  I woke up this morning with a tiny beetle on my pillow.  Probably unrelated, but then again perhaps the invasion has begun!)

Female Click Beetle

Hi again,
Thanks for the additional photos.  Immature Click Beetles are known as Wireworms, and they do not resemble beetles.
