Can you tell me what type of bug this is? Photographed in Israel, August (Summer), may be obvious but I can’t seem to find it anywhere.
Any help appreciated

Hover Fly

Dear Ari,
This is a Hover Fly or Flower Fly in the family Syrphidae, and many members of the family mimic stinging bees and wasps.  Your individual is an effective mimic of Thread-Waisted Wasps.  Though they look like stinging insects, Hover Flies are perfectly harmless, since they neither sting nor bite.  Hover Flies are beneficial in the garden.  Adults pollinate flowers and Syrphid larvae feed on Aphids.

I have a big wasp like bug but it has a furry body. Can you tell me what it is please? It was in a jar of jam three day ago.

Hornet Mimic Hover Fly and Yellowjackets

Unlike the surrounding Yellowjackets that are able to sting to defend themselves or their nest, the Hornet Mimic Hover Fly in the middle of your image neither stings nor bites, so it depends upon its protective mimicry to keep it safe from predators.  Many Hover Flies or Flower Flies in the family Syrphidae mimic stinging wasps and bees for protection.  You can compare your individual to this image on the British Hoverflies site to verify our identification.  We suspect these critters were accidentally attracted to the jam jar when it was unintentionally left uncovered.

Have found several of these on a California native milkweed, Asclepias fascicularis. They are quite sedentary and don’t seem to be eating the leaves or flowers. They are hard to photograph clearly, as the ‘skin’ is oddly transparent.

Syrphid Fly Larva on Milkweed

Dear wev,
We do not recognize your caterpillar, and unfortunately, searching online for caterpillars on milkweed leads to Monarch Butterfly Caterpillars, which this is clearly not.  We will attempt to research this further, but meanwhile, we will post it as unidentified.  Perhaps one of our readers will recognize it.

Ed. Note:  August 16, 2017
Thanks to a comment from Cesar Crash, we agree this is most likely the larva of a Syrphid Fly (see BugGuide ) which would mean it was probably feeding on Aphids.

Hornet Hover Fly

Dear Marion,
We are guessing that Nn84ue is in Wellingborough, UK.  Based on this British Hoverflies image, we believe your Hover Fly is
Volucella zonaria, commonly called  Hornet Hoverfly.

Subject: Green Slimy Bug in Salad
Location: Portland, OR

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.
