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.

Fly Pupa

Fly Pupa

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!

Fly Larvae

Fly Larvae

Dear Megha,
The best information we can provide is that these are the larvae of a member of the order Diptera which contains the Flies, Gnats and Mosquitoes.  They look like the larval form of some type of Fly.  One of you images also contains what appears to be an aquatic True Bug like a Water Boatman.

Rattailed Maggot

Rattailed Maggot

Dear Douglas,
This is the larva of a Drone Fly, commonly called a Rattailed Maggot.
  According to BugGuide:  ” larvae feed on rotting organic material in stagnant water” so we are wondering if there was any water in the rotten tree.

Subject: swarm of caterpillars
Location: Fairfax, VA

This has got to be the most unusual behavior I’ve ever seen – a swarm of small (5 – 8 mm in length), translucent caterpillars, slowly moving across a sidewalk (to get to the other side, of course!) in a stream nearly the width of the sidewalk, with a depth of several individuals. I did not see it from the beginning, but I estimate it took about 15 minutes for them to reach the other side. It was most similar to watching schooling fish, but in slow motion. I assume this is adaptive behavior for the same reason as schooling and herds? This was at 8 AM on a very humid day, if relevant. Any idea as to species? Have you heard of this before? Is swarm the right term?

Fungus Gnat Larvae Aggregation

Fungus Gnat Larvae Aggregation

Dear Seth,
This fascinating phenomenon is an aggregation of Fungus Gnat Larvae in the family Sciaridae.  We generally reserve the term swarm for winged species while in flight.
