Taeniotes scalatus

Taeniotes scalatus

Hi Again Fred,
You are correct that this is a Bycid or Longhorned Borer Beetle in the family Cerambycidae.  After searching fruitlessly for your previous Bycid, we are please to inform you that we believe we have correctly identified this individual as
Taeniotes scalatus thanks to the Cerambycidae de Costa Rica site.

Unknown Longhorned Borer Beetle

Longhorned Borer Beetle is Oedudes species

Hi Fred,
This is such a beautiful Bycid, or Longhorned Borer Beetle in the family Cerambycidae, and we thought it would be easy to identify.  We are troubled that we were not able to find a match on the internet.  Our first lead was this unidentified specimen on Richard Seaman’s FlickR page, but we aren’t even sure they are closely related.  We thought for sure we would be able to identify it on the Cerambycidae de Costa Rica site, but alas, our eyes went blurry we looked at so many photos.  Perhaps eye fatigue caused us to miss it.  Though it looks somewhat similar in markings, the anatomical structural differences don’t quite match on these Crioprosopus nieti we found on the Cerambycidae de Costa Rica site.  The North American Milkweed Borers in the genus Tetraopes that are pictured on BugGuide look very similar in structure and coloration, however the Costa Rican species pictured on the Cerambycidae de Costa Rica site do not look similar.  We hope one of our readers will have better luck with this ID.

Update:  Oedudes species
We received two comments, one suggesting this might be Oedudes bifasciatus and another suggesting it might be Oedudes callizona.  See photos of Oedudes bifasciatus on The Early Birder, on Project Noah and on FlickR and a photo of Oedudes callizona on Cerambycidae Species.

Hi Daniel,
I’m a herpetologist amateur.
I realise that to determinate bugs is very very difficult!
Thanks a lot for the information
fred

You are most welcome Fred.  Your photos are quite lovely.  We have no scientific background and there are no entomologists on our staff, so any answers we provide should be viewed as questionable rather than conclusive.

I didn’t see this one, but my wife found it on our back porch earlier today. It’s March here, and we’d just had an unseasonable snowfall. This guy was hiding under one of the cushions on the lawn furniture. He was about 3 to 4 inches across, and alive but not moving all too fast in the cold weather.

Fishing Spider

Fishing Spider

Dear DaveC,
This magnificent creature is a Fishing Spider in the genus Dolomedes.  Despite the large size, Fishing Spiders are harmless.

Thank you for such a quick response! I’ll let my kids know (4 year old twin boys) — they were more than a little freaked out when they saw it.
Best,
Dave

Bug man,
Can you help us ID this bug? We have tried steam, spraying, cleaning, bombs and these guys keep coming back. I think we have killed very bug on the mountain. My wife says she has been bitten, but I don’t think it’s a bedbug? We live outside of Golden Colorado at about 8300 ft. In a log home.
Thanks

Larder Beetle

Larder Beetle

Dear Robert,
This is a Larder Beetle,
Dermestes lardarius, and it is a common household pest found in stored foods.  No amount of spraying will work if you don’t find the source of the infestation.  We suggest you clean out the pantry and discard old foods.

Thanks Daniel,
We have cleaned the pantry and the house and have not found the source . We will keep looking …at least we have eliminated bedbugs! Like you said these guys keep coming back.
Could the source be dead mice in the basement wall. These are the only framed walls in the house? We also have a really old Freezer.
These guys don’t look like they fly?
Bob

Hi Bob,
We would not rule out dead mice as a food source.  Larder Beetles can fly.

Possibly Milkweed Bugs

Possibly Milkweed Bugs

Dear Fred,
These are not beetles.  They are True Bugs in the suborder Heteroptera.  They remind us of North American Milkweed Bugs in the genus
Oncopeltus.  We tried searching that and found a very similar though not exact photo identified as being in that genus on FlickR.

Orbweaver

Orbweaver

Hi Fred,
This is an Orbweaver in the family Araneidae, but alas, we cannot provide a species identification for you.  It looks similar to the North American species pictured on BugGuide
Verrucosa arenata, commonly called the Arrowhead Spider, but we cannot even say for certain if it is closely related.  Perhaps one of our readers will be able to provide a species identification for you.

Update
We realized we had a very similar image in our archives that was identified as 
Eriophora nephiloides.

Whouawhh! many thanks!
beautyfull colors when it’s a good picture…. not like mine…
fred

We did correct the color to the best of our ability.  See the posting.

A few months ago I sent you a (bad) picture of a spider, named by you:Eriophora nephiloides, and you photoshopped the picture very well, thanks for it! Now, I found by the guy who was with me, a better picture. That’s for your website, OK? thanks!
