Male Dobsonfly I believe
Thanks to your website, i was able to identify this wicked looking critter. I haven’t seen a Mississippi version of this insect on your site, so, i decided to send you one. This must be a young one, measuring between 3 and 4 inches total. It was photographed in central Mississippi in June 2008.

Hi Darrell,
Some of our readers tend to exagerate or miscalculate the size of their insects. Even at 3 to 4 inches, a male Dobsonfly is an impressive insect.

Isabella Tiger Moth eggs, etc
Hello Bugman.
I just found your egg page and I absolutely love it! I thought you might like these photos of Isabella Tiger Moth laying eggs and the resulting larve, otherwise known as Wooly Bear Caterpillar. She laid the eggs on my door jam, and I am rearing them, at least until fall. They overwinter as caterpillars so I won’t try to keep them all winter. They are eating nettles.

Hi Betsy,
We hope you will continue to provide us with Isabella Tiger Moth, Pyrrharctia isabella, metamorphosis images as the caterpillars grow and pupate.

I found this stuck to my trousers and i dont know what it is or were it comes from,but i like to know what it is, i live in Galway Ireland, kind regards

Hi Jeannette
Your caterpillar is a Puss Moth Caterpillar, Cerura vinula. The UK Moths site indicates that the common name comes from the moths resemblance to a cat. The caterpillar feeds on willow, poplar and aspen. Artist Katherine Plymley has a metamorphosis watercolor reproduced online.

Mystery Sphinx Moth Identified!!
Scrolling through your caterpillar pages, I recognized Xylophanes pluto as the larvae of the moth in the photo I sent you a few days ago. I’m raising another one now. Yesterday it molted and changed from bright green to deep brown in a matter of hours. Thanks for your fascinating web site!

We are happy you identified a caterpillar we did not have a chance to write back to you about.

Actually the insect I was trying to identify was the Xylophanes Pluto moth, not the caterpillar. I’m sending the photo again, since I don’t believe you have one in your database.
Keep up the wonderful work!

Hi again Sacha,
Thanks so much for sending us the photo of the adult Xylophanes pluto, but we are a bit confused as you mention a larva and we missed you original email. Do you have a caterpillar photo to add to this posting? Can you provide a location to add to the posting? Thanks. We are copying Bill Oehlke on this email as he is keeping comprehensive data on the species distribution of Sphinx Moths in North America.

Update: (07/20/2008)
Hi Daniel, Here is the text of my original letter, sent on 7/16/08: Maybe you can help me identify this sphinx moth which hatched from a caterpillar I found on my pentas here in Fort Lauderdale, FL. It is similar to the Virginia Creeper sphinx , but different enough that I think it’s something else. I checked through the “moths” sections and didn’t see an identical one. Any idea? Thanks, Sascha In the first letter, I neglected to mention that I’d hatched the moth – or rather, sheltered the larva so I could watch it pupate and hatch. A few days after sending that letter, I recognized the Xylophanes Pluto caterpillar on your website. I didn’t get a chance to photograph the first caterpillar before it changed, but here are some photos of the one I’m currently watching. Although this one is the brown morph, the adult moth featured in the photo was from the green morph. Bill Oehlke might like to know that there are also Tersa Sphinx caterpillars on the same penta bush. I am happy to provide information and photographs for his efforts and yours.

Hi again Sascha,
Thanks for the additional information, the wonderful new photos of the caterpillar, and for assisting Bill Oehlke.

Dynastes tityus female and Glenurus gratus
After a little searching on your website, I identified these two specimens found in my front yard. I live in Missouri below St. Louis. Hercules Beetle, Dynastes tityus female. She is 6.3 cm. (2.5 in.) from the head to the tip of the last leg. You can see the right side of the carapace is cracked because my dad stepped on the poor girl last night and that is how she was found. We released her this morning:

Hi Jenny,
Because it makes it difficult to archive letters with species belonging on different pages, and because we just posted a letter with both a male and female Eastern Hercules Beetle, we will only be posting your lovely image of an Antlion, Glenurus gratus, probably the most magnificent Antlion found in North America.

Please help identify
I am from Southern Idaho (Jerome) and found these two beautiful insects feasting in my garden (well they aren’t feasting in the picture but they will probably be hungry after) anyway – I don’t know what they are? Horneyts? Flies? Squash Bugs? I didn’t write you right away because I was afraid I would receive a "boy your a dummy" response but I searched and searched and didn’t find this insect on your site. Close, but not exact markings. Can you help? Thank you so much for your time. I know you are very busy! Thank you,
Cindy Flowers

Hi Cindy,
We are going to begin by gently chastising you because we were hurt by your implication that we would call you a dummy when you have a legitimate question. It should be apparent that we answer the same question repeatedly (just look at our Dobsonfly pages) and we have even had to identify many times this month our July Bug of the Month, the Cecropia Moth, despite it being posted at the top of our home page. Your Wasp Mimic Clearwing Moths in the family Sesiidae challenged us. We found two possibilities on BugGuide that did not fully convince us, so we turned to the Moth Photographers Group where Paranthrene robiniae looked promising. Then we returned to BugGuide with that name and located the common name of Western Poplar Clearwing, but not too much in the way of information. We then found an excellent Forest Pest page that profiles your lovely moths because the larvae are borers in the wood of willows and poplars and extreme infestations can be very damaging to trees. Your photo is also quite beautiful and we would have been thrilled to receive it even if this wasn’t a new species for our site.
