Subject: Grubs found in rotting wood of coral tree

Good morning, Bugman.
We discovered today a large area of rot on the base of our coral tree. Excavating the rot, I found several communities of this grub pictured. The animals seemed at first not to move at all, but after some time, it became evident that they do move, very slowly.
I am inclined to believe that they are taking advantage of the rotted wood, and are not the cause of it.
They were surely not expecting this sudden exposure!
Can you identify them?

Black Soldier Fly Larvae

Black Soldier Fly Larvae

Dear Swami,
We are nearly certain these are Black Soldier Fly larvae,
Hermetia illucens, which you may find pictured on BugGuide.  Black Soldier Fly larvae are frequently found in compost piles, where they are beneficial as they aid in decomposition.  According to BugGuide:  “Commercially distributed for composting” and “Larvae live in compost, dung, rotting vegetation.”

Dear Daniel,
Thanks so much for getting back to me. Yes, I agree the larvae match the images of Black Soldier Fly larvae on your website.
I am hoping we can save our tree; it seems to be infected with some kind of rot that turns the wood right under the bark to mush. Apparently these larvae love it, as there are quite a few.
Best wishes,
Mahayogananda

Subject: Mysterious “swimming bug”
Location: Salina Turda in Romania
July 31, 2016 2:31 am
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

Probably Horse Fly Larva

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

Subject: Parade of insects in slime?
Location: Hillsboro, Virginia

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.

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.
