Your letter to the bugman:  This guy (girl?) showed up on my patio cover (canvas). It’s about 3 inches long and probably an inch around. (BIG joker). Thought maybe Luna Moth. Some one said maybe Imperial Moth. I know Lunas are endangered and I want to do the right thing. Don’t plan on hurting it or anything just curious about what it is.

Imperial Moth Caterpillar

Dear Curious in GA,
This is an Imperial Moth Caterpillar.  Many Giant Silkmoth Caterpillars from the family Saturniidae and Hornworms from the family Sphingidae pass unnoticed on vegetation while they are feeding.  Fully grown caterpillars then hunt for a suitable place for pupation  They leave the food plant and at that time they are frequently discovered by observant humans.  When we receive images of pre-pupal Imperial Moth Caterpillars, they have frequently turned brown or orange as metamorphosis nears.  Your green individual might still be feeding

Your letter to the bugman:  We see these ‘bugs’ usually in the fall. Their bite is painful and leaves whelps. Wasp killer spray does them in so we got pictures this time.

Possibly Robber Fly

Dear Bob & Elaine,
Normally we would expect a large biting fly to be a Horse Fly or a Deer Fly, and this looks more to us like a predatory Robber Fly, but we have not had any luck matching your images to a species.  While we caution readers not to carelessly handle large Robber Flies as they might bite, we do not know of any reports of unprovoked bites from Robber Flies.  We will be sending your images to Eric Eaton to get a second opinion on its identity.

Possibly Robber Fly

Eric Eaton Responds.
Hi, Daniel:
Yes, it is a robber fly, but I suspect that it is guilty by association with something like a horse fly or deer fly.  Robber flies do NOT habitually bite people.  They are strictly predators of other insects.

Giant Silkmoth: Rosthchildia arethusa rhodina

Dear Trevor,
We also have trouble with
Rothschildia species, so we are contacting Bill Oehlke to see if he can identify the species.

Update courtesy of Bill Oehlke:  September 23, 2019
Daniel, I do not think I previously responded to this one
Rothschildia arethusa rhodina
Jordan, 1911
I anticipated it in Orellana, but I think this is first confirmed report.

Subject:  More images of Fairy Shrimp
Geographic location of the bug:  Florida, St. Petersburg

Your letter to the bugman:  I know i’ve sent fairy shrimp images before, but those were pretty low-quality(sorry about that), so I took some more images!
Some aquarium equipment is visible in the images because i’m trying my hand at raising them- so far so good, they’re comfortable enough to reproduce(it isn’t a very romantic affair…)
All these images are females, as they have their brood pouches full, still awaiting the day where i notice one depositing eggs…..
I still love fairy shrimps more than ever and i’m super happy that i’m able to submit these images, fairy shrimp go largely unappreciated on the internet!

Fairy Shrimp

Dear Chance,
Thanks for submitting new images of your Fairy Shrimp as well as information about raising them in captivity.  As we requested in our response to your previous submission of Fairy Shrimp:  ” We wish you had submitted larger digital files of your images as the quality was somewhat degraded when we formatted the low resolution files for posting.”  Once again we had to increase the size of your 300×400 pixel png file to convert it to a 550×800 pixel jpg.  Please do not reduce the file of your images in the future.  We would much rather decrease the file size of a larger image than to increase the file size which leads to image degradation.

Green Bottle Fly

Dear Marlene,
This looks to us like a Green Bottle Fly,
Lucilia sericata, which is pictured on the Natural History of Orange County and on BugGuide.   According to BugGuide:  “Larvae feed on carrion. Adults take nectar and have been used as pollinators of onions, cabbages and also other Brassicaceae” and “Larvae are used in forensics to determine the age of a corpse, and in medicine to clean up wounds (they feed on partially decomposed tissue, leaving the healthy one alone).”

Salmon Caper Butterfly

Dear Raya,
We identified this Salmon Caper Butterfly,
Madais fausta fausta, on image 1g of The Butterflies of Jordan where it states:  ” The Salmon Caper Butterfly is a rather migratory species with a distribution con- fined to the Jordan Valley and the upper Mediterranean zone. … It seems that it has two broods, one in spring and another towards the end of July.
