Male Black Horse Fly

Dear Hal,
You are absolutely correct that this is a Horse Fly.  More specifically it is a Black Horse Fly,
Tabanus atratus, and the large close set eyes indicate it is a male.  Despite its size, only female Horse Flies bite and feed on blood.  This male is perfectly harmless.

Your letter to the bugman:  Hello, this is the second time I’ve encountered what I believe to be a goldsmith Beetle. Coolest bug ever. The first time was in the backyard a couple of years ago. The second time, was tonight, waiting for me at the front door. I brought it in to show my mother, she was not a fan. I put it back outside to carry on.

Goldsmith Beetle

Dear S. Botzet,
Thanks so much for sending in your awesome images of a Goldsmith Beetle, the beetle allegedly the fictional Gold Bug of Edgar Allen Poe fame.  Your timing is perfect for us to select your letter as the Bug of the Month for June 2021.  The Goldsmith Beetle is described on BugGuide as “A large yellow/green scarab with no elytral markings. Elytra has irregular rows of punctures.”

Daniel is currently in Ohio and he has limited resources since he cannot use photoshop to crop, color correct or resize images, but while working in the garden yesterday, he could not help but to notice this lovely, large Bumble Bee visiting the plentiful dandelions.

Probably Common Eastern Bumble Bee

We believe this is most likely the Common Eastern Bumble Bee, which is pictured on BugGuide, and due to her size, we believe she is a queen.

Your letter to the bugman:  This gorgeous hairy-breeched insect was obsessed with my (non-flowering) cucumber plant. It looks like a fly but I can’t find it in any databases. I checked for wasps and bees, too! Seen April 24th (late spring)

Squash Vine Borer

Dear Jennifer,
This is not a Fly.  It is a Moth that benefits by mimicking a Wasp.  This is a Squash Vine Borer, and since cucumbers are in the squash family, we presume it is a female laying eggs.  You can get additional information on BugGuide.

Your letter to the bugman :  Dear Bugman,
While hiking in the Santa Monica mountains, I spotted this winged beauty. April 24, 2021
I also spotted two other winged creatures on flowers, there were several in the area and strangely didn’t seem to be alive.

Chalcedon Checkerspot

Dear Melanie,
We immediately recognized your lovely butterfly as one of the Checker-Spots and turning to Charles Hogue’s
Insects of the Los Angeles Basin, we identified your individual as a Chalcedon Checker-Spot, Euphydryas chaldecona, and Hogue specifies:  “Though rarely seen in the basin’s flatlands, this species may be quite abundant in the surrounding foothills, visiting flowers in the spring and early summer” and later of the preferred caterpillar food plants “locally they are particularly fond of Sticky Monkey Flower (Diplacus longiflorus), a common native shrub of the coastal sage plant community.”  It is pictured on Butterflies and Moths of North America and on BugGuide and well as here on BugGuide where it it is recognized as a subspecies, Euphydryas chalcedona chalcedona, and where it states on the BugGuide info page that the range is:  “Primarily relatively near the Pacific Coast, west of desert areas, in areas of broken terrain, from northern British Columbia to northern Baja California Norte. Inland in mountains of eastern Oregon and Washington, across northern Idaho and just into extreme western Montana. Also inland in desert mountains across the Mojave and Sonoran Deserts of southern California and Nevada into southern Arizona and perhaps northwestern Sonora.”  It may have appeared “not alive” because it was seen earlier in the day and it had not yet warmed enough so that it might fly.  We cannot conclusinvely identify your images of the Solitary Bee and Wasp.
