Male Black Horse Fly

Dear Moliken,
This is a male Black Horse Fly,
Tabanus atratus.  Observe how close together the eyes are spaces.  That is a sign it is a male.  Female Horse Flies have a noticeable space between the eyes.

Gentle Readers,
When Daniel first arrived in Ohio two weeks ago and he began working in the garden, he encountered a massive Tiger Bee Fly in the garage buzzing around the window.  Daniel tried to rescue it because of the large web building spider (OK he will figure out what they are before he leaved Ohio in two more weeks)  with the sheet web that will run out from its lair if anything falls into its dusty web.  Daniel eventually caught the Tiger Bee Fly in his hands and released it.  When he saw one later in the day, he liked fantasizing that it was the same individual he rescued. 

Tiger Bee Fly

The Tiger Bee Fly likes sunning on the south facing bricks and this morning it allowed Daniel to get really close to just watch it as it basked in the sun on the wreath on the front door.

Bee Killer

Dear Kevin the Curious,
Wow, Ventura California is blowing up with insect identification requests this morning.  We just finished posting an image of a “Conspicua” Lady Beetle from Ventura.  This is a Robber Fly,
Mallophora fautrix, a member of a genus known as Bee Killers because they often prey on large Bees and Wasps.  This is “The only representative of the genus in California”, according to BugGuide, and it is pictured on Natural History of Orange County.

Your letter to the bugman:  Looked like a wasp at first but then Google took me to your site and I think it’s very close to a crane fly you posted. It was sitting on my car at 35 degrees on July 27, 2021

Crane Fly

Dear Dirk,
Your Crane Fly looks like an old posting from our archives that was identified as
Ctenophora ishiharai, and we located this FlickR posting that is identified as Ctenophora nohirae.  We believe the latter is a closer match.

Wow, thanks a lot!
Much appreciated.

Your letter to the bugman:  These photos are taken around a backyard pond in Pasadena Ca. Although I would like to know what species the dragonfly is (it has just emerged and is still clinging to it’s niad shell) my main qestion is in regards to the other photo. What kind of robber fly do you think this is? It’s by far the largest one I’ve seen. The plastic cap of the garden stake next to it is 19 millimeters in diameter.
