Moved from ID Request.

Might be laying eggs
Larvae of these flies are predators of soft bodied insects, so you might have aphids, scale, or some other pest on your trees.

So would this be a beneficial insect? How do I get more information. I'm new to this site and having trouble navigating. Thank you!

Farmers like these because they eat aphids.

Most of the thumbnail links on this site are clickable.

Once on a photo page that is in the guide (rather than ID Request) you will see a row of tabs and a row of names. The Info tab shows you whatever information we have entered about the species, species group, or whatever the page is about. Often it is empty, or you have to go up a level to find the real information.

The list of names, such as

Home » Guide » Arthropods (Arthropoda) » Hexapods (Hexapoda) » Insects (Insecta) » Flies (Diptera) » "Aschiza" » Syrphid Flies (Syrphidae) » Syrphinae » Syrphini » Allograpta

shows each category the insect is in from least to most specific. Allograpta is a genus in tribe Syrphini (all Allograpta are Syrphini but not all Syrphini are Allograpta). Diptera is an order within class Insecta.

Thank you!
Thank you so much for all your help :) Do I need to move the picture too?

Also, I believe I have a few different stypes of these. They all hover but are different sizes and colors. Took care of the aphids in my vegetable garden.


Yes, Allograpta obliqua - yel
Yes, Allograpta obliqua - yellow katepisternum is visible in the other image, distinguishing it from A. exotica.

Thank you for confirmation. Would it be possible to leave me a link to more information about this insect? I'm having trouble navigating the site (newbie)


Thank you!
It seems I have a lot of these helpers buzzing around my home garden this year. They vary in size and color. And totally wiped out the aphid infestation on my broccoli & celery. This is good news since it's only my second year gardening and I was getting a bit aggravated about all the pests eating everything up since I only use organic techniques to control them. Now about those pesky rats...
