Your letter to the bugman:  Hi,
Whilst on holiday in France a couple of years ago we visited the salt pans I’ve located above. Whilst there we found what we think is a beetle larvae that the salt seller told us lived in the salt. Any ideas what it is? the lady told us that they are “prehistoric”.

Fly Larva we believe

Dear Martin and Ruth,
We do not believe this is a Beetle larva.  It looks to us more like the larva of a Fly in the order Diptera, possibly a Horse Fly.  We will attempt further research on this.

Fly Larva we believe

Thanks Daniel, it does look like some of the hose fly larvae pictures, i just can’t find any references to salt loving species. This one literally lived in pure salt!!

Your letter to the bugman:  I saw this bug in my dogs water just floating at the bottoms and didn’t know what exactly it was, I asked family and  they said it was a “moth caterpillar”  I looked up moth caterpillar and I have to admit it looked very similar to this one but this one seems a bit darker and it was still alive after I put it in water added soap AND oxi clean. I ended up smooshing it with my sink drainer making sure it doesn’t like start a nest or something then I let it go down the drain. So what bug is this? Why was it still alive after I drowned it in water soap and oxy clean? Please answer because at first I thought this was some sort of parasite and at this point I’m not sure and I VERY worried for my dog.

Leatherjacket

Dear Marcus,
This looks to us like the larva of a Crane Fly, and it will not harm your dog.  Here is a BugGuide image for comparison.  Crane Fly larvae are sometimes called Leatherjackets because of their hard exoskeleton.  Because of the large amount of rain last year, Crane Flies were quite common in Southern California last year.

Subject:  What’s this bug/worm in standing water?
Geographic location of the bug:  Northern CA – Mendocino Coast

I’ve been seeing a lot of these worm bugs floating/swimming in the standing water on top of my composter.  They are alive and move around slowly in the water.  They’re almost an inch long and kind of skinny if you see them sideways (2nd photo).  Can you tell me what this is?
Thanks so much!

Black Soldier Fly Pupa

Dear Laurie,
This is a Black Soldier Fly Pupa, and their presence in your compost pile is a sign that it is healthy.  According to Daily Dump:  “The Black Soldier Fly Maggots are prolific creatures that appear in all compost heaps – they are nature’s scavengers and good for composting. They love a very wet pile. …  If it’s too much and you want to avoid them coming out and crawling on your floor, you can put your composter in a plastic tub with high sides. They usually cannot crawl out of that slippery vertical surface. If they crawl out and wander all over, then sweep them up, collect them in a container and drop them under a tree – birds love them!  Remember that these BSF maggots suppress the lifecycle of the pest carrying housefly. The Soldier flies have no mouth and cannot transmit pathogens, so they are harmless. Appreciate them. They are even a fried delicacy in some cultures as they are very rich in protein!” 

Black Soldier Fly Pupa

Hi Daniel,
Thanks so much for writing me with this info about the Black Soldier Fly Pupa.  Now when I see them I’ll not be frightened and know that they are beneficial in my compost pile.
I appreciate the helpful info you sent me.
Be well,
Laurie

My three year old is very well known for his ability to spot the most camouflaged objects, insects, anything. He is the best shed  hunter I know. He found an assassin Bug today that I couldn’t even see while he was pointing at it. But he also found this other… Thing. We were deep in the woods, near a swamp as well as a creek. Pine needles for ground cover mostly, but tons of birch, maple, katalpa, just a huge variety of trees. Also, a huge cliff/rock wall. We like to go here because you can find basically anything in this habitat. But we have such trouble identifying them for that same reason. I imagine it’s a simple ID, but I just can’t find this one. Any help would be appreciated!

Flower Fly larva we believe

Dear Devon,
This is an immature insect and immature phases can be difficult to identify.  We believe this is a Flower Fly larva in the family Syrphidae.  You did not provide a size, and most Flower Fly larvae are under a half an inch in length.  If this was much larger than that, please let us know.  There are Flower Fly larvae pictured on Diptera Info and on the Oregon State University site.

Robber Fly Pupa

Dear Chris,
This Thing has been on our back burner as we have tried unsuccessfully to identify it.  We are pretty certain we have a similar posting buried somewhere in our archives among the nearly 25,000 postings we have made in the last 17 years, but we have not been able to locate it.  We believe this is the immature stage of a Fly in the order Diptera, but we cannot provide any internet citations at this time.  Perhaps one of our readers will help to identify this Thing.

Update:  Thanks to Christopher Taylor who sent a BugGuide link to a Robber Fly Pupa.

Subject: Green Slimy Bug in Salad
Location: Portland, OR
August 12, 2017 9:59 am
Howdy,
Found this in my salad after eating at a restaurant. It moved like a leach out of water. Able to elongate its body unlike any maggot I have seen before. No ribbed texture like a maggot. Greenish hue slimy, semi transparent able to see some innards. No obvious mouth parts.
This was in Portland, OR on August 7th. Salad was local organic greens. Wandering what it is for health reasons.

Possibly Flower Fly Larva

Dear Harlan,
What we sacrifice in not getting pesticides in our food is the occasional appearance of an insect in organic produce.  This looks to us like the larva of a Flower Fly in the family Syrphidae, like the one in this BugGuide image.  Syrphid Fly larvae are beneficial predators that eat large quantities of Aphids, and it makes sense that they might be found in organic greens.
