Your letter to the bugman:  I found this little bug on the screen outside my indoor plants. Between 1 to 1.5 cm. in size. I’ve never seen anything like it before. I’ve looked through all kinds of sites, but little true info is out online. I can’t identify any that look quite like this.
Please help?

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.

Your letter to the bugman:  This fly(?) has been flying around my deck.  He is about 1″ long.  He seems to like sitting on this light colored umbrella, but he does land on darker surfaces.

Tiger Bee Fly

Dear NancyA,
This impressive fly is a Tiger Bee Fly, a parasitoid that preys on Carpenter Bees.  According to the Missouri Department of Conservation:  “The female tiger bee fly deposits her eggs in places where carpenter bees have laid their eggs. The bee fly larvae eat the carpenter bee larvae.”

Thanks!  I thought I had not successfully submitted that email and photo, but
I guess I had!  I figured it out from a combination of searching the
WhatsThatBug web site and an Internet search and I was astounded to find out
what it is.  I definitely have carpenter bees.  In fact, one is giving me
trouble in the very table that the umbrella is stuck in that the fly was
sitting on when I took the photo!

Bee Fly

Dear Lilya (the future scientist),
First let me congratulate you on knowing that you want to be a scientist at such a young age.  This is actually a Bee Fly in the family Bombyliidae, most likely the Greater Bee Fly,
Bombylius major, which is pictured on BugGuide.  According to BugGuide:  “A common and widespread bee fly, often seen taking nectar on early spring wildflowers or seen hovering in sunny patches in woodlands.”
