That’s my best guess. Can’t find much on size or range, but this guy seems a bit big (about honeybee size) for that species. Also, don’t know if he’s supposed to be here.

What’s That Bee?

Hi Matt,
Based on images posted to BugGuide, this could well be
Diadasia enavata, but we cannot be certain.  We will post your letter and photos and perhaps someone with more knowledge of Solitary Bees will be able to assist in a species identification or confirmation.  Your photos are quite nice.

Which Bee is it???

What am I seeing?

Hi Daniel –
Another pic attached for you, strange one.
What am I seeing here?
We have 10 Italian Cypress appx. 25 ft. tall here that we found the
Sawfly Larva on.  Did not want to take a chance on losing them so I
sprayed them all with Spinosad to kill the larva very early this morning.
Went back a few hours later to see if any of the larva were dead, collected
a few twigs in a plastic pail.  Some larva were dead, some still alive.  Shot
some pics and ran across the attached image.
Is this a newly hatched Sawfly of some other type of insect?
Thanks –
Lou Nigro

Sawfly Larva and what might be a Chalcid Wasp

Hi Lou,
We are creating a brand new posting for this image and linking to your original submission.  The other insect looks like a parasitic Hymenopteran, possibly a Chalcid Wasp.  There are some similar looking Chalcids, but they have larger hind legs.  Perhaps it is just the camera angle.  The Chalcid is a Parasitic Hymenoptera.  The female lays eggs within a host, usually the larva of a moth, fly or beetle.  It stands to reason that they might also parasitize Sawfly Larvae.  Most parasitic Hymenopterans are host specific.  It is possible that this Sawfly that is underrepresented on the world wide web has a species specific parasite that preys upon it.  We are going to tag this posting as Food Chain even though much of our response is speculation. 

Eric Eaton identifies the Mining Bee
The “wasp” is a bee in the genus Perdita.  How it got there I have no idea.

Hi Daniel –
Looks like you are right on, took a few more shots from different angles.
Could be a species specific one as the coloring is a bit different.
Depth of field this close is limited, wish the pic was sharper, will shoot a
few more later.

ETTL, manual exposure, handheld.
I’m glad to see that there are wasps in the area, even though I killed some of them,
that are helping me out.  Further spraying will be kept to a minimum.
Wasp measured appx. 2mm in length.
Thanks –
Lou

Hi again Lou,
Since we were wrong about the Wasp and it actually being a Bee, we suspect it was collateral damage from your insecticide.  We are not sure why it was found on the Sawfly.

These wasp-looking creatures are in about 1/4 of the flowers on my dogwood this year. The tree seems very healthy otherwise.

Solitary Bees on Dogwood

Dear CV,
These are some species of Solitary Bee and they are beneficial.  As such, this should not be referred to as an infestation.  We believe your bees are in the family Megachilidae that includes Mason Bees and Leafcutter Bees and you can see many examples of these bees on BugGuide.  Though the detail in your photo is limited and we cannot make out the exact identity of your species, the individual that is facing the camera appears to have a light face.  That doesn’t seem to match the appearance of the Blue Orchard Mason Bee that is pictured on a dogwood blossom on this informative posting on the Pencil and Leaf website.

probably Andrena males, not Megachilidae.

Further to the Blue Banded Bee

Hi guys,
As pointed out in the link you provided on my previous picture, the males of this species cluster together and hang by their jaws (?)at night from a grass stem or leaf. Here is a shot taken late afternoon on a very overcast day of a pair settling in for the night.

Blue Banbed Bees

Hi Trevor,
Thanks for sending this further documentation to augment your original submission of a Blue Banded Bee.  Aggregations of male Solitary Bees bedding down together for the night, a phenomenon known as a bachelor party, is not an unknown occurrence on our website.

One for your collection

Hi guys,
Seems you don’t have this guy in the database, or at least the search engine didn’t bring it up for me. These guys, the Blue-banded Bee – Amegilla cingulata, are becoming a very important pollinators for commercial crops as the Small Hive Beetle infests many European Honey Bee nests in Queensland and wipes them out.

Blue Banded Bee

Dear Trevor,
Thanks so much for providing us with another wonderful and underrepresented species from Australia.  We are able to link to the Brisbane Insect website which has some nice images of the Blue Banded Bee.  As you indicate, with modern threats to domestic Honey Bee populations, Solitary native bees are becoming increasingly important as pollinators.

Meet at the Red Barn in Elyria Canyon Park at 9:30 AM.

The Coyote Melon is a squash plant that has taken root in the meadow near the big dead walnut tree, and it is beginning to set fruit.  This sprawling plant is a native and it can be found wild on the hill on a winding hairpin curve above La Abeja restaurant on the East Side of Mt Washington in the Greater Cypress Park Neighborhood.

Coyote Melon Plant

We expect native bees are pollinating the blossoms and perhaps getting trapped inside when the blossoms close.

Update:  September 25, 2011
Due to a very low turnout of volunteers and the absence of one of the cohosts, the work party ended a bit early today after plants in the nursery were watered and some Castor Beans and Poison Hemlock were pulled out.
