Hi Guys,
Working on my photo exhibit I am looking at a Metallic Sweat bee with green head and thorax and striped yellow/black abdomen. There is a characteristic I don’t see mentioned in your previous evaluations about which I’d like to know your thinking. This bee’s wings, at rest, are broadly parted, while other bees you’ve talked about held their wings tight against the body. It is on a sunflower. Taken in July 2011.

Hi Carl,
My what a small and low resolution image you have sent to us.  While resting with wings folded over the body is the typical position used by Sweat Bees while visiting flowers, as you can see from this image on BugGuide, parted wings do represent a possibility.  Perhaps your particular Sweat Bee had just alighted, or it was just preparing to take flight.

Hi there,
Saw this on my bush in my garden, at first i thought it was a group of seeds, until i looked closer, just wondering what they were, and if they were anything to worry about.

Bachelor Party of Longhorned Bees

Bachelor Party of Sweat Bees

Dear Curious,
This is a Bachelor Party of male Longhorned Bees in the tribe Eucerni, but we are not certain of the species.  Male Bees do not sting, so they pose no threat to you.  You can see similar images of Bachelor Parties from North America in our archives.

Update:  February 5, 2014
We got a comment that these might be male Green and Gold Nomia Bees,
Lipotriches australica, a type of Sweat Bee that also exhibits this Bachelor Party behavior in Australia.

Hi Bugman,
These guys have been all over my rose mallow flowers for the last few days in the evening (5-7pm). They zip around quickly until they decide on a flower, spend about 10-20 seconds inside, and emerge covered in pink pollen. They are about 3/4 inch long. They don’t seem to be very interested in the other kinds of flowers in the yard. This is in Cleveland, OH, about a half mile from Lake Erie, on the side of the house facing the lake. It has also been very warm here for the last couple of days — upper 80/lower 90 temps. Thanks very much for your help!

Dear Laura,
This is a Metallic Sweat Bee in the family Halictidae.  There are numerous species that look quite similar.  See BugGuide for additional information.  Here is a Metallic Sweat Bee sent in exactly two years ago that reminds us very much of your image.

Hi again, I do think I’ve now managed to identify these as Metallic Sweat Bees, thanks to your wonderfully informative site.

Bugman, the wasps and bees really like this particular hemlock weed with many colorful varieties visiting it today. Looks like a Metallic Sweat Bee, a Digger Wasp, and one other black/white wasp. Would the black wasp with white bands possibly be a type of Mason Wasp?

Hi Roger,
Generally we don’t like making postings with diverse insects, but all your pollinators are in the order Hymenoptera, and they are all visiting the same blossoms for the same reason, to feed on nectar, so we are making an exception.  We agree with your identifications of the Metallic Sweat Bee which looks very much like this image on BugGuide, and the Digger Wasp,
Scolia dubia.

The third wasp is most likely a Potter Wasp and we believe it is in the genus Eumenes, which you can find pictured on BugGuide, however, we were not able to confirm a species identification.

Leaf Cutter Bee gathers Pollen
Location: Mount Washington, Los Angeles, CA
We have been spending part of the day in the garden tending to things and taking photos of insects.  We managed to capture a single photo of one of the wary Leaf Cutter Bees that has been gathering pollen from the Rudbeckia that is currently blooming.  We have seen them in the past on Rudbeckia as well as Cosmos, but for some reason, we have no more Cosmos and we haven’t tried planting more seeds in recent years.  The awesome thing about the Leaf Cutter Bees is that they gather pollen on the underside of their abdomens.

We also managed to get a single shot of this equally wary Metallic Green Sweat Bee before it flew off.  Seems when we don’t have the camera handy, there are three or four Metallic Green Sweat Bees buzzing around the Rudbeckia and they let us get very close, but as soon as the camera appears, off they go.

Hi! Last year we noticed a few all-green metallic sweat bees in our garden (burrowing – sent you the pics). Now we’re seeing a different type of sweat bee: smaller with a green metallic head and thorax; black-and-yellow striped abdomen. They love the blooming artichoke. There’s a skipper in one shot, to provide perspective.

Metallic Green Sweat Bee

Hi Tracy,
This is another Sweat Bee in the family Halictidae, and we believe it is most likely in the genus
Agapostemon based on the photos posted to BugGuide.  We will see if your Metallic Green Sweat Bee submitted last year is in our archive.  Back then you thought it might be Agapostemon texanus and females of that species are all green while males have striped abdomens according to BugGuide images.  We would say that chances are last year you photographed a female and this year a male.  We also find these Green Metallic Sweat Bees on cardoons, a wild member of the artichoke family, in our Mt Washington, Los Angeles neighborhood.
