Over the last couple of days I found two of these in the bath tub now another one on bathroom rug. I have scowerd the internet trying to identify this as would like to understand where it could be coming from. It has no legs. I’d be surprised if they entering through the high up bathroom window. Then I thought they coming through plug hole… but now I find one on the floor I’m not so sure. Would love to know if you can help. Many thanks. Jelena

Rat-Tailed Maggot

Dear Jels,
The identification is easy, but your other theoretical questions are not quite as easy.  This is a Rat-Tailed Maggot, the larva of a Drone Fly, and according to BugGuide:  “larvae of most feed on decaying organic debris. They are filter feeders in different kinds of aquatic media. They purify water by filtering microorganisms and other products.”  Since we don’t know where your bathroom is located:  on the 37th floor of a high rise, in a basement, in Singapore or in New York, speculating on the point of entry is questionable, but we suspect they are breeding in your drain.  If you are connected to a septic tank, this is even more likely.  We suspect these Rat-Tailed Maggots are now seeking a drier environment so they can initiate pupation.

I found this pretty bug flying around my bush and I don’t recall ever seeing one before. It’s purplish wings were really pretty in the sunlight. Could you please identify it for me?

Ichneumon: Trogus pennator

Dear Caitlin,
The long antennae on this magnificent wasp caused us to correctly speculate it must be an Ichneumon, and we quickly identified it on BugGuide as
Trogus pennator.  According to BugGuide:  “Trogus pennator is a parasitoid of swallowtail butterflies (Papilionidae), ovipositing in the caterpillars.  The solitary larva develops inside the caterpillar, allowing it to pupate before killing it. After metamorphosing, the adult wasp chews an irregular hole in the chrysalis to escape.”

Hi Bugman,
We saw this bug crawling around on a rooftop bar last night. It apparently had been hanging around on the umbrellas and plants.
Any idea what it is? It looks prehistoric. Very cool.

Female Dobsonfly

Dear Amanda,
The mandibles on this female Dobsonfly are indeed quite impressive, and she defends herself quite well with them if she feels threatened.  The male Dobsonfly, on the other hand, has impressively large mandibles that are not really functional.  He uses them to battle other males and to impress female Dobsonflies during mating.

This little guy is sitting on my patio door here in Minnesota. He doesn’t move. I have not seen a bug like this before or at least one with its wings open like this. I’m curious to know what it is.

Plume Moth

Dear Becky O,
This is not a feathered fly.  It is a Plume Moth, a member of the family Pterophoridae, and upon glancing through BugGuide, we believe we may have identified the species as
Geina sheppardi.  According to BugGuide:  “Larvae feed on wild grape (Vitis).”

Can you help please?
I was wild camping in a wood near Princes Risborough, Hertfordshire last night and this beast fell out of a tree onto my mate’s arm.
Do you know what it is?
Incase this isn’t clear from the pics, this is his wrist, so the bug was about 6cm long. It seemed to rear up??
Many thanks

Lobster Caterpillar

Dear Ben,
Though it looks nothing like a typical Caterpillar, this Lobster Caterpillar is actually the immature form of a Moth in the family Notodontidae.  According to UK Moths:  “This unassuming species gets its English name not from the adult moth, but from the remarkable crustacean-like appearance of the caterpillar.”

Dear Daniel,
Thankyou so much for your reply. Was it unusual to find in the UK/Princes Risborough? I’ve Googled and seen a Japanese one that looks very similar
Best regards
Dear Ben,
The Lobster Caterpillar ranges throughout Eurasia, from England to Japan.  There are several British sites that include the
Lobster Moth Caterpillar, including UK Safari.
