Your letter to the bugman:  In my aunts garden the statchys is blooming. There are so many different pollinators, including many honeybees. This insect caught our eye. It hovers, has drone-like flight. It is visiting the flowers but it is very attentive to the competitors. It’s spends about as much time attacking honeybees as it does visiting flowers. When it attacks it seems like it bites. We see many honeybees on the ground with half of a wing, in apparent suffering- It seems they have been hurt or intoxicated

Woolcarder Bee

Dear Mollyanne,
This is a male, non-native Woolcarder Bee, a species native to Europe but present in North America since the mid 1960s.  According to BugGuide:  “Males defend their territory very aggressively not only against other males but also against other flower visitors” which explains the behavior towards Honey Bees that you witnessed.

Your letter to the bugman:  Good Morning,
Spring has sprung here in the Carolinas. I was watching the bees on a holly bush when I saw two bees, one much smaller than the other. The smaller bee got on the back of the larger bee, shook him like crazy and stole the pollen from his legs! Is this common in the bee world?

Mating Eastern Carpenter Bees

Dear Mike,
This looks to us like a pair of mating Eastern Carpenter Bees,
Xylocopa virginica, and the male, who is on top, has a white face.  We do not think pollen thievery was on his mind.  According to BugGuide:  “Adults take nectar from many flowers, often biting into base of flower to “rob” it without pollinating (but seen to pollinate Passiflora incarnata quite effectively–pollen is deposited on thorax).”

Dear Daniel,
Thank you so much for the ID on my bees. Little did I know that I was interrupting an intimate moment! My son was morning the grass and the larger females were everywhere that there was a flower of any kind. Do three Carpenter bees sting? My son was terrified by then but they really didn’t seem to care about me, walking right up to them. I do remember from my childhood in CT, that there was a best of Carpenters in the garage and they would dive bomb us.
The picture that I took was that of the bees in a Holly bush. There were hundreds of them.
Thanks again for the education. I love What’s that bug!

Hi Mike,
Male Carpenter Bees are incapable of stinging, and females are not aggressive and rarely sting.

Your letter to the bugman:  I’ve noticed a new pollinator in our gardens this summer but don’t recognize the species.  I’m estimating 20-25MM in length, fairly robust, but not “chunky” like a bumble bee.  I saved one in our pool and grabbed a couple closeups of their uniquely colored eyes.  He/she flew away safely  :-]

Thank you for the response.  I see many similarities, however the size, shape, and coloring of the eyes do not correspond.  Head scratcher.  :-]

Eastern Carpenter Bee

Hello again,
Because you wrote back, we took a look at all your images and we believe you have submitted images of two different species.  We still believe the individual on the flowers is a Bumble Bee, but the one you saved from the pool appears to be an Eastern Carpenter Bee.  Check out the similarity in the eyes with this individual posted to BugGuide of
Xylocopa virginicaMale.  As you can see from this BugGuide image, the Eastern Carpenter Bee has a dark colored abdomen, which is why we feel certain you have submitted two different species.  Since you rescued this individual, we are tagging the posting with the Bug Humanitarian Award.

I’m sorry for creating confusion!  …but am grateful for your extra effort :-]
Thanks guys!!

Your letter to the bugman:  Hi! I got this lovely picture with my macro lens – thought you might like to add it to the page for this bee! 🙂

Metallic Sweat Bee

Dear Elizabeth,
Thanks for sending in your lovely image of a Metallic Sweat Bee.  We generally don’t even attempt to identify them beyond the subfamily Halictinae because we don’t have the necessary skills to differentiate them further.

Your letter to the bugman:  Hi Daniel,
I was out in my pollinator garden snooping around this morning and discovered a large number of these small bees.  Size is about 1/3 inch.  They were in an area of my garden that has a bee house, but were not showing any signs of using it.  I am wondering, however, if these are mason bees?  Any help gratefully appreciated!
And I’m looking forward to a buggy summer.

Solitary Bee

Dear Deborah,
While we agree this is a solitary Bee, we are uncertain of its exact identity.  It might be a Squash Bee, one of the Longhorned Bees in the genus
Peponapis.  According to BugGuide:  “these solitary ground nesting bees pollinate Cucurbitaceae more effectively than honeybees and line their brood cells with a waxlike material they secrete”.  Do you have squash in your garden?  We would not rule out that they might be Mason Bees in the family Megachilidae, which is well represented on BugGuide.  We believe that with many solitary Bees, males emerge earlier and they will patrol areas where there is both abundant food as well as favorable nesting areas in anticipation of the appearance of females with which to mate.  Male Bees will not be interested in your bee house.  We look forward to future submissions from your “pollinator garden”.  Perhaps one of our readers who has more experience keying out Solitary Bees will provide a more conclusive identification.

Your letter to the bugman:  Some sort of bee sits on the same screen each spring and then seems to die. This year there are two. Do you know what kind of bug this is. Looks like a big bee.

Possibly Eastern Carpenter Bees

Dear Michelle,
There is not enough detail in your image to be certain, but based on your description that they are big, and based on the fact that our editorial staff is currently just outside of Youngstown, Ohio and we have witnessed male Eastern Carpenter Bees on the wing right now, we suspect your visitors are also Eastern Carpenter Bees.

I didn’t want to get too close! I think you are right about being a carpenter bee. They never leave the screen though. Lazy carpenter bee maybe? Haha
Thanks for your input and prompt response. We have a big garden so maybe they are just waiting.
