Greetings, What’s that Bug Volunteers!
I am happy to say the bug activity in my Rain Garden is finally picking up. I was wondering how long that would take, so I am now relieved. I watched a Leaf Cutter Bee cut a leaf and fly off with her prize for her nest. I witnessed a Monarch Butterfly lay an egg on a Milkweed stem. I’ve seen TWO Great Black Wasps on the Milkweed. The Soldier Beetles are back in abundance, as are the Cicada Killer Wasps. The Northern Paper Wasps like getting drinks at the birdbath. And the aphids are emerging on the Milkweed so I expect the lacewings and lady beetles will soon arrive, along with those tiny parasitic wasps.
The photos I’ve attached are of a black bee which has proven quite challenging to photograph. I finally caught it on a late Miniature Hollyhock blossom over this past weekend. I like the pollen sacs on the legs. I have Bumble Bees of various sizes in my garden; this though does not appear to be a Bumble Bee.
Can you help me out?
Blessings to one and all,

Black Bee

Female Two-Spotted Longhorned Bee

Hi again Wanda,
How nice to hear your rain garden is thriving.  We just hear yesterday that Southern California may be expecting a dry “La Niña” winter next winter, though since our predicted wet “El Niño” winter last year was a bust, all bets are off on what will really happen.  In our memory, miniature hollyhocks are about an inch across, which would make this black Bee about half that.  Are we correct?  We suspect this might be a Carpenter Bee, and we are requesting assistance from Eric Eaton as we cannot provide you with anything specific at this time.

Daniel:
Female of the Two-spotted Longhorned Bee, Melissodes bimaculatus.  Males have antennae about twice as long as the females.

Greetings, Daniel et al!
Yes, your memory is correct. Miniature Hollyhocks (Sidalcea sp) blossoms are an inch or just a tad larger. Quite prolific here and terrific pollinator draws; not as magnetic as Milkweed, Liatris or Monarda, but still good draws.
Speaking of milkweed, I noticed an overabundance of Large Milkweed Bug nymphs last week. And I do mean overabundance. The aphids don’t annoy me since I know my integrated past management system will address that issue. The large Milkweed Bugs though, well I guess I live with them or remove a colony here and there with snippers and a plastic bag …
Exciting to hear I can add a new insect to my list of photos! A female Two-spotted Longhorned Bee! WooHoo! She’s quite a “tease” in that she never landed long enough for me to focus and photograph until recently. Glad she was hungry long enough for me to take her picture!
Hope you are safe where you are in CA; I keep praying for rain where it is needed and dry where it is too wet.
Thank you yet again for your assistance in helping my insect list grow!
Blessings,
Wanda J. Kothlow

I thought when I took this picture that this was a fly, but it isn’t. Is it a native California bee? I like those antennae.

Longhorned Bee

Dear Dirk,
This is a male Longhorned Bee in the tribe Eucerini, and we haven’t the necessary skills to taxonomically identify it further.  According to BugGuide, they are:  “Hairy bees, typically with pale hair bands on the metasoma. Males typically have very long antennae. ”  BugGuide also states:  “Nesting is in the ground for all species. Known nests are vertical burrows in flat ground.”  We have several great images on our site of “bachelor parties” which are aggregations of male Longhorned Bees that spend the night together.

Hello, I am contacting you because in August I got a photo of this white bee with green eyes. I live in extreme south Ontario in Essex county if you want to know where I saw it. This bee was the size of a Honeybee and was calm. I could get close to it too.

Dear Bugman,
Can you help me identify these adorable fuzzy bees? I believe they are a native species. They are very docile, feeding on coneflowers, I can gently touch their abdomens. They enjoy watering time, as it is quite hot and dry! There is also a couple of other species of small bees in the pics. Thanks so much. My father and son love your site!

Bee Flies

Bee Flies

Dear Kate, Nature Lover,
Though they resemble Bees, most of the insects in your images are Bee Flies in the family Bombyliidae, probably in the Tribe Bombyliini which is pictured on BugGuide.  Bee Flies and other True Flies can be distinguished from other insects, including Bees, because Flies have a single pair of wings and most other insects have two pairs of wings.  Bee Flies, which do not sting, benefit from their resemblance to stinging Bees.  One of your images includes a single Bee Fly on the same blossom as what appears to be a Longhorned Bee.

Hello! I would love your help in identifying this cluster of bees I spotted in the early morning on one of my sunflowers. Someone I asked thought they were long-horned bees. Could that be right?
Thanks!

Bachelor Party:  Male Longhorned Bees

Bachelor Party: Male Longhorned Bees

Dear Katy,
We agree that these are male Longhorned Bees in the tribe Eucerini, and according to BugGuide, they can be identified because they are:  “Hairy bees, typically with pale hair bands on the metasoma. Males typically have very long antennae.”  Since you found them early in the morning, they probably spent the night in this aggregation that is sometimes known as a bachelor party.

Hello and howdy do!
Here are two photos of solitary bees supping nectar from Arizona sunflowers in August of this year. I wonder if you can verify the tribes of said bees (or even specific species!) by these two photos. Thank you so much for your time.

Male Longhorned Bee

Dear T. Stone,
We agree with your Longhorned Bee identification from the tribe Eucerini, but we are not certain of anything more specific.  The orange antennae are distinctive, and they are also evident in this photo from BugGuide of a member of the genera
Melissodes or Tetraloniella.  There is a photo on BugGuide of a female member of the genus Melissodes that looks like your other photo, so we would not rule out the possibility of your photos representing a male and female of the same species.  Here is another photo from BugGuide of a male member of the genus Melissodes with the orange antennae.

Eric Eaton Confirms, and cautions about Accuracy with species differentiation.
Daniel:
Two bees in the Apidae tribe Eucerini.  I am not sure how they can be identified beyond tribe from images alone, especially since Arizona is an epicenter of global bee diversity.
Hope you had a nice holiday.
Eric
