Hi,
Here’s a small fly that I pulled out of the bird bath last week. The photo isn’t great, but I’m hoping it’s good enough for you to be able to identify.

Yellow Masked Bee

Hi Anna,
We realized when we first looked at this photo two days ago that it was a bee and not a fly, but we did not have an identification, so we did not write back.  We have now identified this little creature as a Yellow Masked Bee in the genus
Hylaeus, thanks to this photo posted to BugGuide.  According to BugGuide, there are over 50 species in North America, and we do not have the necessary skills to identify this individual beyond the genus level.

Many thanks for the id on this little bee.  Maybe one day I’ll finally stop mixing up my bees and flies.  I don’t have many bees that plunk themselves into the birdbath, and this was a very small one.  My eyes aren’t what they used to be!
Anna

Spider eating bee

My friend in Mill Bay on Vancouver Island, BC Canada took this picture this morning on his daisies. A voracious little white spider that is enormously successful capturing and killing other insects. What is this spider’s name?

Crab Spider Eats Bee

Hi Sharon,
The scientific name for your spider is
Misumena vatia, and it has several common names, including Crab Spider because of its general shape, and Flower Spider because of its habit of waiting on flowers for pollinating insects.  Crab Spiders are able to change color to match their surroundings, and your white Crab Spider blends perfectly with the white petals of the blossom.

At least I think it’s a native bee. It’s not a honey bee, and the flower is a native. As a secondary identification request, I’m curious about what voracious and unseen bug is eating the flowers

Long-Horned Bee

Hi Barbara,
This is a Long-Horned Bee in the tribe Eucerini, but we are not certain of the species.  We spent the entire morning editing the presentation for tomorrow, and just when we whittled the images down to the best, you send in this candidate.

Larvae on a Log
Location: Audubon, PA

Dear WTB, While I was reorganizing my woodpile, I came across this larvae nest and found it very interesting. I never saw anything like it before. After I took the picture and scraped the nest off of my log, the yellow substance was a really fine powder, kind of like pollen. Do you have any idea what these little worms will turn into?

Possibly Bee Nest provisioned with Pollen

Dear Cheryl,
Please forgive us.  We absolutely cannot research this tonight.  It was a long day (14 hours of teaching, monitoring, attending awards and scholarship presentations, and conducting SLO assessments.  The students actually accused us of being grouchy today.  The end of the semester is rough.  Enough of that.  We believe this is a Solitary Bee Nest and we believe the yellow substance is Pollen.  Time will tell.

Unknown Group of Bees
Location: Portland Oregon

Hi,
I took this photo about 4 years ago. I found this group of smallish bees on a dandelion. I have no idea what they were doing or why they were there. I found it very curious.
I know we have quite a variety of bees here. I also know they are not honeybees (I’m a beekeeper).
Anyway, they were quite beautiful and if you could help solve the mystery that would be fantastic.

Longhorned Bees: Bachelor Party

Hi Damian,
We believe these are Longhorned Bees in the family Eucerini.  BugGuide has a similar image posted that is identified as
Melissodes communis.  This communal roosting behavior is not uncommon in the family, and the members of the aggregation are males, hence they are called Bachelor Parties.

Is this a bee?
September 7, 2009
This insect was photographed in in early September, it looks a lot like a digger bee but it’s eyes are brown and not green. I have searched the net and all of my bug books but can’t ID it! Help!
Thanks, Rhonda

Carpenter Bee, maybe

Digger Bee

Hi Rhonda,
Our first inclination is that this is some species of Carpenter Bee, but it doesn’t match the images on BugGuide.  We will check with Eric Eaton who may be able to assist in the ID.

Correction from Eric Eaton
Daniel:
Wow, what a fantastic image of a very active bee, a female in the genus Centris, family
Apidae.  I hope Rhonda considers posting this to Bugguide, as we have few high-quality images of this genus.  Dr. John Ascher is an expert on bees, and he visits Bugguide frequently..  He could probably identify this specimen to species.  Centris bees are solitary, like the overwhelming majority of native bee species, each female digging her own nest burrow.
Eric

Daniel,
Thanks for the prompt reply- and thank you and Eric Eaton for the ID- wonder how he knew it is female, amazing! If you want to post this image to Bugguide, you have my permission to do so, if you need a higher res photo just let me know (please include photo credits). Thank you again for the help.
