Subject:  What is this?
Geographic location of the bug:  Central NJ (Edison)

I saw this creature as I was taking a walk. It was fairly large in size – about 1 1/2 to 2 inches in size. I saw it just now right after Thanksgiving. I did a reverse image search. Google proclaimed it a stag beetle. Bing returned a lot of pages from Japan. The shapes and colors are correct, but the wings are too small. The two wings on this picture are tiny stubs. Beetles have full wings that cover the abdomen. Hornets have transparent wings.

Oil Beetle

Dear David,
Your claim that “Beetles have full wings that cover the abdomen” is true in most but not all cases.  This is an Oil Beetle, a species of Blister Beetle in the genus Meloe.  Oil Beetles are flightless.  There are other species of Blister Beetles with vestigial wings like this Spanish individual, and many species of Rove Beetles like the Devil’s Coach Horse also appear wingless, though their wings are described on BugGuide as “elytra short (about same length as pronotum, or only slightly longer; wings are functional in most), typically exposing 3-6 (usually 5-6) abdominal segments.”

Thank you for your reply. I was beginning to wonder if this was an invasive species.
I did an image search on Bing (Google said it was a stag beetle) and it pointed me to a bunch of Japanese pages (in Japanese, of course) with pictures of very similar looking bugs. One site (via Bing translate) identified it as a “miyamatsuchihanmjou” which wasn’t much help, but there was a note attached calling it a type of blister beetle and warning me not to touch it. (Not that I had any desire to do so).
I guess the Japanese maybe more attuned to nature, but seeing all of these Japanese pictures and none in America, I feared it was an invasive species.
I see that these live in my area of New Jersey and are mainly active in the spring.
Again, thank you for the quick ID.

Hi again David,
North America also has Oil Beetles that are active in the fall.

Yes. I saw they’re active all year. By the way, this specimen was between 1 1/2 to 2 inches in length – much larger than the ones you have posing by the quarter. I was hoping to have a quarter or some object to put in the picture in order to judge its size, but didn’t have anything. I also resisted the urge to pick it up and move it somewhere with better contrast. I’m glad I did.
I found one species called a “short winged oil beetle”. This specimen was about the size of the one I saw and was also found in New Jersey during freezing weather.
I see the larvae live in flowers, hitch a ride on a passing bee, and live in the hive eating honey, pollen, and bee larvae.

Subject:  Whose pupal cases (?)
Geographic location of the bug:  southern Colorado, ponderosa pine forest

Last spring I cut and split some ponderosa pine firewood in the woods behind my house. Some pieces sat up there all summer, and when I brought them down this fall, I discovered these pupal cases (?) on one chunk. I was curious to know what made them.
(Resending because my images might have been too large last time)

Exuviae of Fungus Beetle Pupae

Dear Chas,
These are the exuviae or cast off exoskeletons of the pupae of Fungus Beetles, probably
Gibbifer californicus.  Here is a similar image from BugGuide.  According to BugGuide:  “Larvae feed on wood-destroying fungi” and “female lays eggs in bark crevices of fallen rotting logs.”

Dear Daniel Marlos,
Fascinating! thanks a lot — now I know where to go for further research.
It was a standing, dead beetle-killed pine, so decay had already started in
some places on the trunk.

Hi there! This guy was trying to rent a room from us (in South Caribbean of Costa Rica). We successfully removed him from our front door, but curious what kind he was?

Probably Nursery Web Spider

We believe this is a Nursery Web Spider in the family Pisauridae, possibly one of the Fishing Spiders, but its markings are unusual.

I’ve seen that someone have asked for an hymenopterian from Colombia, and I’ve seen that is very similar to this one I ask for.
It was in may 2016, but not in Colombia but in Tanzania.
What do you think?

Sausage Fly

Hi Ferran,
That Hymenopteran from Colombia is still unidentified, and it does bear a resemblance to the Sausage Fly you have submitted.  Sausage Flies are male Driver Ants in the genus

Subject:  Moth? Butterfly? What is this blue lovely?

This beautiful butterfly/moth was on our front porch when we got home today. Posted it to facebook and no answers yet. I thought it was a moth because I’ve never seen a butterfly with it’s wings folded like that. My mom thinks it’s a butterfly because the antennae are not fuzzy. What is it? It’s still outside several hours later. Pretty little critter! Thanks!

Great Purple Hairstreak

Dear Shara,
We are very excited to post your lovely image of a Great Purple Hairstreak, a Gossamer Winged Butterfly.  Though we have several images in our archives of this species, we have either images showing the closed wings, or we have images of recently emerged individuals with wings not yet fully expanded.  We suspect your individual has also recently emerged from a pupa, and it was perhaps not quite ready to fly when your encounter occurred.

Thank you for the response! This is sad though. It must have let us so close to take pictures because it was already dead. It was upside down on the rug today when I returned home (It was windy outside) Still beautiful, but a small chip is missing from the wing and the antennae fell off 🙁 Sad to think that it had just recently emerged and died so soon. I’ve brought it inside for now.

Subject:  Bug? Slug? Parasites?
Geographic location of the bug:  Kitchen, beds,hallway  everywhere

Hi am have looked everywhere I can online and nothing. But I keep finding these chunks and some look like crumbs. I have even seen smaller very similar shapes in my daughters stool. (Sorry gross but I have). In my home it is myself and my 2 children 3 and 6 years old we all have are own bed and every morning we find this stuff in our beds. Seems like they start off a gray tan color and as they dry up turn orange? Not sure.

Organic Substance?

Dear Curious Mom,
While we are uncertain of the actual identity of the chunks and crumbs you find in the beds in your home, we are quite confident they are neither bugs nor slugs, which leaves parasites or other.  The things in your images look vaguely organic, and our first thought was ear-wax or mucous.   If you suspect there is a malady involved, you should seek professional medical advice.
