Your letter to the bugman:  These two were battling it out, but the wasp won in the end. I thought it may have been a cicada killer, but this one was all black, maybe a little Blueish.

Great Black Wasp and Katydid Prey

Dear Karin,
We are thrilled to be able to post your wonderful images of a female Great Black Wasp and her Katydid prey.  The wasp has stung and paralyzed the Katydid and she it trying to get it back to her underground burrow.  She is probably climbing the table to give her some height so she can take off and glide toward her nest.  According to BugGuide:  “Provision nests (in burrow in soft earth) with Katydids or grasshoppers. ”  Also commonly called Katydid Hunters, these solitary wasp are not aggressive toward humans.

Heady Maiden Moth

Dear Ivan,
This is a diurnal Tiger Moth in the subfamily Arctiinae, and we previously identified it as a Heady Maiden Moth,
Amata cerbera, and we received a comment identifying it as Amata mogadorensis, but with no explanation on how to distinguish the two species.  Lepiforum has images of the latter and iNaturalist has images of the former.  At least we know the genus is correct, and we are going with the Heady Maiden Moth because we like the common name.

Dear Daniel,
Thank you for your prompt & comprehensive reply, I am really impressed with your service.
Kind regards,

Dog Day Harvestfly

Dear JS,
Though it is commonly called a Dog Day Harvestfly because of its end of summer flight time and because it resembles a giant fly, the Annual Cicada is not a true fly.  Cicadas are also well known because of the cacophony they produce from tree tops.

Lovely! Thank you Daniel! 🙂

Ed. Note:  There has been some chatter on Facebook accusing us of making up the common name Dog Day Harvestfly.  According to BugGuide, of the genus Neotibicen:  The name ‘Dog Day Cicada’ is most often applied in particular to Neotibicen (Tibicen) canicularis. Other common names encountered:  Harvestflies, Dryflies, Jarflies.”  BugGuide also note on the page for :  “Other Common Names Dogday Harvestfly, Harvestfly, Northern Dog-Day Cicada, & Common Dog-Day Cicada” with the explanation “DOG-DAY: a reference to the hot ‘dog days’ of late summer when this species is heard singing; at this time in the northern hemisphere the Dog Star (Sirius) is above the horizon in the Big Dog constellation (Canis Major).  NOTE: Dog-days of summer indeed do refer to Sirius, the dog star, and although it is above the horizon, it is not visible in summer in the northern hemisphere. This is because it is up during the daytime. Canis major is a “winter” constellation. Canis Major CANICULARIS: from the Latin ‘canicula’ (a little dog, the Dog Star, Sirius) HARVESTFLY: another reference to the late season song of this species, heard during harvest time.”

Your letter to the bugman:  It is around as big as a Canadian nickel. Very weird, looks like a parasite. It has 6 legs and two antennae on its little head. Grey and sorta fuzzy. I would like to know which species this is, and if it’s dangerous or not. Thank you!

Masked Hunter

Dear Michael,
The Masked Hunter is not a “parasite creature” but rather, a stealth predator.  Immature Masked Hunters have a sticky exoskeleton that attracts lint and other debris to effectively mask it to help it to blend in with its surroundings.  While not dangerous to humans, a Masked Hunter might bite if it is carelessly handled.  Masked Hunters have adapted quite well to cohabitating with humans, and it will help to control Cockroaches and other unwanted household pests.

Small Squaregilled Mayfly

This proved to be quite a challenge for us, but we eventually found this BugGuide image (which is eerily similar to your image) and this BugGuide image of a Small Squaregilled Mayfly in the genus Caenis.  There is a nice image on Yobi Adventures.  Mayflies have aquatic larvae and adults are generally found near bodies of water.  We believe you were mistaken in your interpretation that it was trying to burrow into the siding of your house.  Mayflies are popular bait for fly fishermen and many tied lures used by anglers are patterned after Mayflies.
