Spider from Connecticut
I know you are busy this time of year, but I found this spider (the second one in three days) in my year in Northwest Connecticut. A couple of things, could you tell me what kind it is and what is the thing underneath it. Was it feeding or is it something else? Thanks for your help. Attached find a macro photo of one of the spiders.

Hi Jim,
This is a female Dolomedes Fishing Spider and she is carrying about her Egg Sac in order to protect it from harm. These large frightening spiders are quite harmless, and in addition to their maternal instincts, they are fascinating creatures.

Can you identify this bug??
Hello! I found this bug on my screen door — it stayed there for three days and then it was gone — do you by chance know what it is? I live in Virginia if that is of any help. Thank you,

Hi Terri,
This etherial beauty is a Luna Moth. We started to get photos from the South this year in early March, and by late May we were getting sightings from Maine and Canada. Your photos represent a second generation in the South. Where warm weather prevails for longer periods, the Luna Moth has a second generation that will overwinter as a pupa inside a cocoon wrapped in a leaf that falls to the ground and remains under the snow buried in the fallen leaves.

Male Dobsonfly Photo
After reviewing your site, I quickly descovered that this is a male Dobsonfly. I was surprised to find it on next to my front door this morning. I live in Robertsville, MO and I see bugs all the time, but this one is new to me. Have these been common in Missouri, or are they relocating in the changing climate?

Dobsonflies are local for your part of the country, but they are dependant upon a nearby water source. Year to year normal climate changes do affect yearly insect populations.

Blue sand digging wasp?
Hi there bug guys.
I am from Ontario, Canada and was out in my driveway yesterday and noticed this blue waspy looking bug digging in a pile of sand. It was quite a sight. He would go in and appear a moment later with a ball of sand under him, which he would then shove out from underneath himself before going right back at it again. He was a pretty little bug too. Shiny blue wings on an almost ant like body. I was wondering if you would be able to identify him for me and maybe explain what he was doing digging so ferociously in the sand as he was. Thanks so much,

Hi Sarah,
When your Cricket Hunter, Chlorion aerarium, finishes her nest, she will provision it with paralyzed crickets and related insects and lay her eggs. You can look at BugGuide and the Cricket Hunter Wasp page for more information on these digging wasps.

Correction: (08/01/2008)
The cricket hunter wasp from Ontario is actually the “great black wasp,” Sphex pennsylvanicus, most likely. Hard to definitively exclude Podalonia, but I am quite certain it is that Sphex species. She’ll bring katydids, not crickets, back to the burrow.

“Tarantula wasp”?
While on vacation in Arizona, we were hiking in the desert and came to an area where we were almost being chased off by this flying insect, the we saw why, attached photos we took very carefully, but what am amazing sight to see, I know the “T” was paralyzed, but that’s a big arachnid to be carried away by a bug. Anyway my question is, what’s that Bug?

Hi Melissa,
Your wasp is a Tarantula Hawk, a Spider Wasp in the genus Pepsis. The female Tarantula Hawk will drag the paralyzed Tarantula to a burrow and lay an egg on it. Adult Tarantula Hawks are frequently found drinking nectar on Milkweed and other desert flowers. We are lamenting that your photo isn’t of a higher resolution because we would have loved to crop and enlarge it.

Fly Picture
I captured this beautiful looking fly in late July in Dublin, Ohio. Please could you identify. Thank you.

Hi Andrea,
Collectively, the flies in the family Syrphidae are known as Hover Flies, Flower Flies or Syrphid Flies. Your species is a real beauty, Spilomyia interrupta.
