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.

Green Bee or Wasp

I saw this bee (or wasp) on our Mexican Petunias today in northeast FL. It has a bright green head and thorax, and a black and yellow striped abdomen. I looked for information here and on BugGuide and found the Metallic Green Bee (Agapostemon splendens) which looks like my bee. However the size is listed as approximately 10-11mm. The Mexican Petunia flower is 2” wide, about 50mm, and this bee looks larger than 10-11 mm on the flower, doesn’t it? Can you help?

Metallic Sweat Bee

Dear Karen,
We agree that this appears to be a Metallic Sweat Bee in the genus
Agapostemon, but we cannot identify the species for certain.  BugGuide does not list a size range on the genus page.  Your individual looks very much like this photo from BugGuide and it is listed as being between 1 and 2 centimeters.

Thank you for your help! The photo you referred me to does look like the bee I saw, and the size range of up to 2 cm seems more in line with the actual size of my bee. I enjoy your website very much–I’ve learned a lot since I found it, and I appreciate all you do. I’m a special education teacher and I’m hoping to use What’s That Bug with my students later on this school year–I think they’ll be fascinated.

So I look up, and there are 20 of these in my kitchen. I’m in Phoenix, AZ, its August, they can fit on my pinky nail, very small, iridescent green thorax and head, abdomen is striped black and yellow like a bee. Its hard to tell if its a wasp or a bee, but the morphology tells me bee. Any info would be appreciated, Thanks!

Saw two of these iridescent green bees yesterday. They burrowed in the soil below our fig tree and did lots of hovering in the vicinity. They were no more than 1/2” in length. One had pollen, the other didn’t. I’m guessing halictidae agapostemon texanus… but would love for the experts to weigh in. Thank you!

Metallic Sweat Bee

Hi Tracy,
We agree that you have photographed Metallic Sweat Bees in the family Halictidae, but we are very reluctant to agree to a species or even a genus identification of this confusing family. 
We are especially thrilled with your photo that shows a Metallic Sweat Bee digging.  According to BugGuide, the are:  “Typically ground-nesters, with nests formed in clay soil, sandy banks of streams, etc. Most species are polylectic (collecting pollen from a variety of unrelated plants)”

Your photos are an excellent addition to our website.
