I have no idea what this could be
Location: Osa Peninsula, Costa Rica

This photo was taken at Bosque del Cabo Rainforest Lodge in Costa Rica, located on the Osa Peninsula by the resident biologist (I believe his name is Philip). He isn’t sure what it is either, so I thought this would be a good place to try to help him find out what it is. My best guess is that it’s a weevil species, but I really have no idea.

Brentus anchorago

Hi Crysta,
You are correct that this is a Weevil, and it presented quite a challenge for us to get a proper identification.  We believe it is a male
Brentus anchorago, and we first identified it on this FlickRiver website after considerable searching.  This entomology website confirmed that identification.  It is also represented on BugGuide with two mounted specimens, a male and a female, and we can deduce that your individual is a male.  Perhaps the nicest images are on FlickRiver.

Hi there. I have seen this guy twice now and have no idea what kind of critter it is. Any ideas? Thanks much.

Tomato Hornworm parasitized by Braconid Wasp

Hi Bill,
The caterpillar is a Tomato Hornworm, and it has been parasitized by a Braconid Wasp.  The female Braconid Wasp lays her eggs inside the body of the Hornworm, and the larval wasps feed on the tissues of the Hornworm.  Eventually, the Braconid Larvae burrow to the surface and form cocoons, which is what you are seeing.  Here is a nice set of images from BugGuide.  The Hornworm will not live to metamorphose into a moth.

what is the name of this beetle

We found the following beetle on July 1st, in Orem UT, at a public park among the wood chips. It was 7 p.m. at night and there were several of these beetles walking around the wood chips.

Cottonwood Stag Beetle

Hi Dante,
This is a male Stag Beetle in the genus
Lucanus, but your location in Utah is a bit far west for the species we usually receive.  We did some research on BugGuide, and we believe this is a Cottonwood Stag Beetle, Lucanus mazama, and if we are correct, this represents a new species for our website.

Cottonwood Stag Beetle

Wow thanks for getting back so soon.My five year old son is an avid bug lover and he thought it was great that he found these beetles. What’s funny is he insisted that they were a type of stag beetle, but we couldn’t find them on the web. It’s interesting you say they’re a bit far west because we saw between 20-30 in the playground. He’d like to know what they eat. Thank you for your info it’s been helpful.

Hi again Dante,
We should probably clarify what we meant by our “west” comment.  Most of the North American Stag Beetle submissions we receive are from two species, the Reddish Brown Stag Beetle,
Lucanus capreolus, and the Giant Stag Beetle, Lucanus elephus.  The furthest west we know of for those two species is Texas.  Your beetle is a different species, the Cottonwood Stag Beetle, Lucanus mazama, and BugGuide has only received submissions from Arizona and we have never received a submission of that species prior to your letter.  You can try feeding your Stag Beetles overly ripe bananas or other very ripe fruit.  Stag Beetles are believed to feed on tree sap, but there is not much available information that we are aware of regarding the feeding habits of Stag Beetles in the wild.
We are fascinated by the wood chip connection.  We just located these reports from Europe (they have their own species there), that Stag Beetles are being found in places landscaped with wood chips.  This is the best article we have read online in a very long time.

Dear Bugman,
Can you identify the Bug and the prey in this picture. The Picture was shot at Dandeli Forest, in North Karnataka, India.

Predatory, CannibalisticRed Bug

Dear Bhavesh,
In our opinion, the predator and prey look like the same species, or at least closely related species.  We cannot even be certain that this is an instance of predation, because some normally plant feeding True Bugs can be opportunistic, and they will feed upon the fluids of the dead bodies of insects without actually preying upon them.  We will need to do additional research to try to determine the identity of this Bug.  There is a very similar looking insect identified as a Cotton Stainer that can be viewed by scrolling down this Rings of Silver website.  The Cotton Stainers pictured on this site also look similar, but with an additional black mark.

Update:  January 20, 2015
We just received a comment indicating that this is a predatory Red Bug
 Antilochus conqueberti, and we found images that match on this site.  The Journal of Entomology and Zoology Studies has published a paper on this predatory Red Bug.

Red and black flying bug

Can anyone identify this insect? When it flies, the parts of the wings near the body are a spectacular red; at rest, the black wings show red spots.
We have spotted these in two locations near the coast in Yorkshire (U.K.) in June.

Six Spot Burnet

Hi Mike,
According to the UK Moths website, this Six Spot Burnet is a common diurnal species.

Thanks. I’ve looked in our books, tried a few Websites, but I couldn’t find it! So thanks for your help.
I’ve seen lots more in the last few days, so they must be common, but I’ve noticed any before.

What is this?
Location: Boulder, CO — Rocky Mountain foothills

I ran across this insect while hiking in the hills around Boulder, CO. It’s about the size of my insect finger, and it flies as well. Otherwise, the picture should give you all the details you need.

Giant Robber Fly

Hi IngridM,
This is one of the Giant Robber Flies in the genus
Promachus.  The species that are pictured on BugGuide all look quite similar and we do not feel confident taking the identification to the species level.
