Noticed these (11) egg sacs in our Aloe barberae tree, and I have never seen anything like them in my life. I haven’t found the mama yet, but after looking around I am guessing them to be from the Bolas spider. LOL, I was ready to call the State bug authorities and have them terminated, but from what I read, they are harmless moth eaters so I will let them be. They are still a bit scary to look at.

Dear Gman,
We agree that these are Egg Sacs of a Bolas Spider, and we concur that the adult Bolas Spider is harmless as well as being difficult to find as they resemble bird droppings.

What insect do you think laid these eggs? We found them in Northern Virginia, maybe 10 miles from the Washington Dulles airport. My son is extremely interested in spiders and insects. He (6 years old) can identify stinkbug eggs.

Carolina Sphinx eggs on Datura

Carolina Sphinx eggs on Datura

Dear John,
When it comes to identifying immature insect stages for plant feeding species, it is very helpful to know the plant upon which the insects were found.  This leaf looks like it belongs to Jimsonweed or
Datura, and several Hornworms from the genus Manduca feed on Solanaceous plants.  We believe these eggs are those of a Carolina Sphinx, and that they will hatch into Tobacco Hornworms, a species known to feed on the leaves of tomatoes and peppers as well, though Datura and Nightshade are native plant hosts for the species.  This image from BugGuide supports our identification.

Thanks so much!!  My son is going to be a huge fan of your website.

Hello Mr. Bugman,
My mother sent me picture and asked if I knew what kind of “bug” it was. She was pretty creeped out, since it looks so wild and crawls all over the outside of her house, but so far has not strayed far from that location. For the life of me, I couldn’t think of anything that looks like this besides Cambrian era arthropods (haha), so I was hoping I may have luck with you. If not, don’t worry about it!

Mantis Ootheca

Mantis Ootheca

Dear Francisco,
This looks like the Ootheca or Egg Case of a Preying Mantis, and it also appears that it has already “hatched” releasing several hundred tiny, predatory Mantises into your mother’s yard where they will help to control insect populations.

Rodent Bot Fly Ovipositing

Bot Fly Ovipositing

Dear s+r,
You images are a thrilling addition to our archives.  This is a female Bot Fly in the genus
Cuterebra, and she appears to be in the process of laying eggs, the “white/transparent goop” that you observed.  Rodent Bot Flies are parasites of rabbits, mice, squirrels and other rodents.  According to BugGuide:  “Females typically deposit eggs in the burrows and “runs” of rodent or rabbit hosts. A warm body passing by the eggs causes them to hatch almost instantly and the larvae glom onto the host. The larvae are subcutaneous (under the skin) parasites of the host. Their presence is easily detected as a tumor-like bulge, often in the throat or neck or flanks of the host. The larvae breathe by everting the anal spiracles out a hole (so they are oriented head-down inside the host). They feed on the flesh of the host, but only rarely does the host die as a result.”

Jeff Boetner, Bot Fly expert, provides some information.
Hi Daniel,
Nice pics. This is a relative of your mystery FL bot from a week or so ago. But this one we can ID as Cuterebra fontinella fontinella. This is a nice shot of a freshly emerged female. The fontinella bots are known for the white rumps on the last segment of the rear end. This is a huge female, they can lay over 1,000 eggs in their short lives. Most eggs are laid in mouse runways or near burrows. The fluid you saw was likely because the female just emerged from her pupae (in the soil). Bots have no mouth parts or digestive tract so no need to poop. They have to store up all their energy they need as adults, by feeding as a maggot in the mouse host, and this one did a good job of that, judging by her big body size. This one is a specialist on white-footed mice, Peromyscus leucopus. This species is our most common bot, yet not found as often as you would think. I have trapped over 200 mice per hectare*. in our plots in MA, and sometimes 80% will have 1-2 bots, so you would think there would be huge numbers out there. And yet many entomologists I have met, have never seen one in the wild. So consider yourself lucky…(or unlucky if you are a white-footed mouse).
Jeff

*a hectare is approximately 2 1/2 acres.

Thanks a lot for the quick answer, dude/dudette(s)! We weren’t expecting close to this quick of a response. I’ll be sure to bug you again for some more IDs (hohoho).

I found these on the back on a raspberry leaf from a plant I bought a few weeks ago. I’m guessing they’re stink bug babies, but not idea what type! Any help identifying them would be great. I’m located just outside of Bristol in the south-West of England

Stink Bug Hatchlings

Stink Bug Hatchlings

Dear Lisa,
As you suspected, these are hatchling Stink Bugs, and they bear a striking resemblance to hatchling Brown Marmorated Stink Bugs,
Halyomorpha halys, which you can verify by comparing to this image on BugGuide. We are well aware of the rapid spread of this invasive Asian species in North America, but we did not know of any UK sightings, so we did some research.  According to a November 2014 posting on BBC News:  “An agricultural pest dubbed the stink bug could establish itself within the UK, according to a scientist.  Entomologist Max Barclay said it was ‘it is only a matter of time’ before the brown marmorated stink bug arrives in the country.  Two of the insects have already been found on imported timber headed for Britain.  The bug, which is native to the Far East, has already reached France and Germany.  Mr Barclay, from London’s Natural History Museum, told the Daily Mail newspaper: ‘I think the brown marmorated stink bug will establish a population here. It is only a matter of time.  It will make its presence felt fairly quickly because it comes into people’s homes in the autumn and winter.’  Its name comes from the putrid stench it releases from its glands when threatened.  The insect was first found in the US in the late 1990s, but has now spread across much of the country. Since then, it has become a severe pest of fruits, vegetables and ornamental plants.”  You might want to report this sighting to your local agricultural agency.  It is possible that the invasive Brown Marmorated Stink Bug eggs were on the raspberry plant when you purchased it, or it is also possible that they are already established, but passing unnoticed in your area.  It is also possible that this is a different species of Stink Bug.

Female Boll's Sandroach with Ootheca

Female Boll’s Sandroach with Ootheca

Dear Jen,
While this is a Cockroach, the good news is that it is not a species that infests homes.  This female Boll’s Sandroach,
Arenivaga bolliana, is basically an outdoor species and she must have accidentally wandered into your home.  We would urge you to relocate her outside.  You can compare your image to this image on BugGuide.  According to BugGuide:  “The downy females have no wings and burrow in the dust under houses and in natural rock shelters where they feed on packrat droppings.  This large roach is also present in abandoned Atta texana [Texas leaf-cutter ant] tunnels and in chambers filled with nest refuse.”  Your female Boll’s Sandroach is carrying an ootheca or egg case.
