Subject: Mysterious “swimming bug”
Location: Salina Turda in Romania

Hello,
Could you help us with the identification of this one?
During the holidays in Romania (salt mines called Salina Turda) we found a strange worm in one of the outdoors swimming pools. It was floating on the surface and at first we thought it’s a piece of plant, but then we noticed it was “shaking”. There was about 8-10% salinity in the water, so we took the bug outside, worried that it may be in pain. Later we put it into the wet mud, near the salty pools and normal river, so it could return to salt waters if it in fact was its natural enviroment.

Some facts about the worm:
– It wasn’t longer than five cm. No legs, no visible eyes nor mouth, only small bump and long stick from the other side.
– Its “skin” was really soft in touch, but on the sides of the body it had sharp ridges and small spikes.
– It was moving in a really strange way, using this long stick (tail?) to push itself. He was suprisingly fast outside of the water. When bothered, it was freezing with it’s tail holded upright.
– More about the tail, it has few tiny hair on the end.

Some more facts:
– It was the middle of July (18th).
– Except of those salt pools, there was plenty of normal water.
– People around didn’t recognize the species.

Can you help us? We wish we could knew what it was.

Probably Horse Fly Larva

Dear Tourists,
This is definitely Dipteran, and we believe it might be a Horse Fly Larva.

I saw this streak of ‘slime’ on my sidewalk yesterday, about 1/2″ wide and 8″ long which was moving slowly as if flowing forward. It was composed of tiny whitish oblong insects, maybe smaller than a grain of rice which were moving forward in unison in this ‘matrix of ooze’
Photo shows streak of slime on sidewalk. The colors are about the same. I took a short movie of the movement but the file is too large to send.
Hope you can help.

Fungus Gnat Larvae

Fungus Gnat Larvae

Dear Sandy,
These are Fungus Gnat Larvae in the family Sciaridae.  According to BugGuide:  “Sometimes abundant enough to form a crawling mass of several inches across and several feet long, similar to armyworm migrations. Can be pests in greenhouses and in commercially grown mushrooms.”

Oh my GOSH!!!!  Thank you so much for the quick answer.  I will use you again.  How very interesting.  I will search for more about them.
Thank you thank you.
Sandy

Horse Fly Exuvia, we believe

Horse Fly Exuvia, we believe

Hi again KyLee,
We already wrote back that this is the exuvia or cast off exoskeleton, but we were not sure of the species.  It sure looks Dipteran, or fly-like to us, so we continued to research.  We found this very similar looking exuvia on BugGuide that is identified as being from a Horse Fly.  We are pretty confident your kids found the exuvia of a Horse Fly.

Wow! Thank you so very much. I knew you folks could help us. Now we will look up the horsefly and study it.  I truly appreciate your time and effort.

This past week we keep finding these outside our front door, and only at night. It doesn’t have legs, it does have weird black stuff at one end of it, everyone says it looks like a larvae or something but they move like a caterpillar.

Dear Kaitlyn,
This looks like the immature stage of a fly, a larva or a pupa, similar to this Black Soldier Fly larva on BugGuide.  Is there a nearby compost pile?

I found this bug in my house along with my dogs. I am concerned that it is some sort of parasite, but was not able to identify it yet. If you know what this is it would surely ease my mind and worrying.

Rodent Bot Fly Pupa

Rodent Bot Fly Pupa

Dear Keith,
We believe this is a Rodent Bot Fly Pupa, an internal parasite that is usually very host specific.  Since you found it in the home, we are surmising the host may have been a mouse or rat.

Please help me figure out what type of bug this is. I’m assuming it’s in larval stage. The ants that have taken over my home were attacking them while they crawled out of the bottom of a dusty closet and I want to make sure I’m not providing an environment for them to thrive or whatever they do.

Maggot

Maggot

Dear Freaked out in Florida,
This looks like a Fly Maggot to us.  Maggots often wriggle away from where they are feeding to find a drier location to undergo pupation.  Maggots often feed on putrifying organic material.  People often find Maggots when they forget to take out the garbage or if some food is left rotting, forgotten in the home.  Maggots will also feed on dead animals and it is possible that something died in the walls.

Thank you! I have never seen them at this stage before and was totally freaked out but I didn’t want to kill them until I knew what they were. However, after I asked you I did discover that indeed something had died in the crawlspace so at that point I knew what they were and the maggots were dropping out of a crack from the crawlspace to the closet. Seriously disturbing…I love most bugs, spiders in particular, but these guys turned me into a huge wimp! Thank you so much for your timely response!
