We found a couple of these gorgeous pupae attached to grave stones. The photos were taken in mid September. I was hoping you could help with identification.

Variegated Fritillary Chrysalis

Dear Jen,
Your pupa is the chrysalis of a Variegated Fritillary.  Because the caterpillars feed on a large variety of plants, they are a wide ranging species in open fields and along roadsides.  According to BugGuide:  “Larvae feed on Passionvine (Passiflora), Violets & Pansy (Viola, Flax Linum, Moonseed (Menispermum), Mayapple (Podophyllum), Stonecrop (Sedum), Purslane (Portulaca) and others. Adults are fond of flowers, and especially seem to like Thistles and yellow Composites. They also frequently visit damp ground.

Leafy Spurge Hawkmoth Caterpillar

Dear science project,
This stunning caterpillar is a Leafy Spurge Hawkmoth Caterpillar, a Eurasian species.  According to Bill Oehlke’s Sphingidae of the Americas website:  “The leafy spurge hawk moth, Hyles euphorbiae (length: 2-3 cm, wingspan: 5-7 cm), was the first classical biological agent released against leafy spurge in the United States, with approval for introduction granted in 1965. Populations of this insect are present in several western states, including Montana, Idaho, North Dakota, Minnesota and Oregon. The moth was also introduced from Europe into Ontario, Canada, and then into Alberta where specimens are occasionally still taken.

Metamorphosizing Bug in Puerto Vallarta, Mexico?
Location:  Puerto Vallarta, Mexico

Hi Bugman!
First and foremost, I wanted to say that I think what you’re doing here as an educational (or shall we say, ”ent”ucational!) service is awesome! I truly hope that you achieve the dream of meeting up with Martha one day and I’m pulling for you! Secondly, I was hoping you could identify this bug which was sighted by my twin sister during her brave, charitable, summer journey via bicycle from Arizona all the way to Panama. It was found metamorphosizing or perhaps laying eggs, as it remains unclear to the layman viewer what exactly is happening, although I suppose one would think as a ”layman”, I could at least identifying egg laying properly. Please excuse the bad pun, and I hope that doesn’t hurt my chances of getting this enigma identified! So, in your expertise, what is going on in this picture, and by which kind of bug? Your knowledge and eagerly anticipated response is greatly appreciated! Thank you!

Urgent ID priority escalation! Re: Identification Request: Metamorphosizing Bug in Puerto Vallarta, Mexico?
September 20, 2010  11:50 AM
Hello again Bugman!
Perhaps it was the letter riddled with awful puns the first time or just the mere fact that you are a staff of single digits fielding an onslaught of mail from the masses on a daily basis, however, I have yet to receive a response from my original inquiry below, and in light of this, I wanted to provide an update regarding the request.  In the event that the puns were the turn-off in the first place, I hesitate to apologize for “bugging” you, as this will certainly not help my chances of getting some closure on this insect any time soon, but I am sorry for disturbing you, as you are a busy guy, especially with the release of the new book which I can’t wait to get my hands on!  (No, honestly, I mean that, and this was not said in hopes of getting my question answered sooner, I promise.  But does it help?)  Okay so to make a long story short, although it looks as if we’re too late for that, the identification of this bug is the subject of a heated bet, in turn, escalating the urgency of this request, as it’s not just any bet…it’s a bet with a guy who always has to be the one to know it all.  He cannot stand being wrong, and no matter what, he insists on being right, and the most unfortunate part for the rest of us is that he IS RIGHT most of the time.  He claims that the insect appearing in our photo is a queen termite laying her eggs, however, to be quite honest, we’re not so sure about that, and think we may have finally entrapped Mr. Trivia into admitting he is human and fallible!
He wanted me to assert what I thought it was, however, I have held him at bay merely by telling him that it’s NOT THAT.  I’m running out of time, however, in committing to an actual answer, as he keeps probing for a more definite response.  Now, of course, if you do indeed identify it as being a queen termite laying eggs, then I will quietly thank you, and hope that he doesn’t stumble upon “What’s That Bug” for more ego stroking satisfaction that we certainly don’t need to see!  Though, should our bug turn out to be something NOT of the termite family, then we can consider this a win-win, as I revel in proving him wrong, and you would shortly receive an incredible spike in web traffic, as there are legions of us who would like to see that just once, Mr. Trivia hiccuped with an answer!  Just to be clear, the bet is a friendly one of no material value made between rivals, and there is no money being changed hands here, nor is someone going to lose a house, car, or spouse as a result of high stakes betting.  So, the pressure is off, Bugman, in terms of being responsible for someone’s life going down the tubes in response to a bug identification, however, let us not underestimate the value of being able to reference this slip up on his part, basking in eternal glory from the point of a non-termite identification, on!  Thank you again for your consideration to elevate the priority of this review!
Sincerely,
Paco and Brunilda

Dear Paco and Brunilda,
Collect your debt.  This is no termite, queen or otherwise.  It is a Caterpillar, more specifically a Bagworm in the family Psychidae.  Bagworms are known for constructing bags from silk and bits of plant material from their food plants, like leaves, stems and conifer needles.  We were not familiar with any Bagworms that make strictly silken bags, so we turned to BugGuide and found an example from Arizona in the genus
Oiketicus that looks very similar to your Bagworm.  Since insects do not respect international borders, it may be the same genus as your example.  Sorry for the delay, but we can only answer so much mail.

Hi Daniel!
Thank you so much for taking the time to identify the little border crossing Bagworm who I suppose didn’t want to stick around to see what ultimately would come of the Arizona SB 1070 Immigration Laws (SB standing for Suspicious Bagworm, of course), if he/she was on the run (or as much as this little critter can try, anyway)!  We cannot tell you how liberating it feels to finally conquer Mr. Trivia in what, at times, became a rather bugly battle of aggressive words, and thanks to you, the win was literally in the BAG!  I’ll stop with the “pun”ishment now, I promise.  Thanks again, and best of luck in the future with all your endeavors!

Dear Carlos,
We do not receive many requests from Honduras.  Your spider is
Nephila clavipes, the Golden Silk Spider or Banana Spider.  The female, represented in your photo, is about 50X the size of the diminutive male.  The silk in the web of a Golden Silk Spider is very strong and gold in color, and small birds are known to become ensnared in the webs.  The spider in your photo has not yet reached full size.

Sycamore Tussock Moth Caterpillar

Sycamore Tussock Moth Caterpillar?

Thanks to your site I think I’ve identified this as a Sycamore Tussock Moth Caterpillar. We’ve seen many of these all over the place this summer. They’re hard to photograph; they don’t like to be still.
Also I’ve seen something very similar to this but with more black than orange hairs spiking out. Is it a variation of the same creature?

Hi again Resa,
We are quite happy to hear that you successfully self identified your Sycamore Tussock Moth Caterpillar,
Halysidota harrisii, which is profiled on BugGuide.  The closely related Pale Tussock Moth or Banded Tussock Moth, Halysidota tessellaris, has a caterpillar with black tufts instead of orange tufts and it also is a local species for you.  It is also profiled on BugGuide.

Can you please help me identify this insect that appears to have 4 eyes. i have never seen anything quite like this anywhere. was very friendly during vacation near Kingston Ontario. We named it the Raspberry Fly because of its colour and approximate size being close to a raspberry. the picture attached is cropped. It is sitting on a friends palm.

good afternoon, I understand your staff is small, i was just wondering what the screening process is. I sent in a picture of an insect I and anyone I show the picture to has never seen before. the title was “Strange Fly” (September 7th, 2010) I was hoping to send friends links to you site to see the bug.

Tachinid Fly

Dear Joe,
A name is much nicer than the interrogative punctuation mark you used on your original request.  We apologize for never responding to your original request, but as you indicated, we do have a small staff.  One person, The Bugman, responds to as many letters each day as time not spent on the time clock teaching college classes allows, and then The Bugman posts selected letters to the internet.  A second staff member oversees the running of the website, ensuring that the web browsing public has the highest quality service that our means permit.  This fly is a Tachinid Fly, possibly
Hystricia abrupta, which you may see on BugGuide. This group of Tachinid Flies are parasitoids on caterpillars.  Here is the explanation posted to BugGuide:  “The most common hosts are caterpillars. Most tachinids deposit their eggs directly on the body of their host, and it is not uncommon to see caterpillars with several tachinid eggs on them. Upon hatching the larva usually burrows into its host and feeds internally. When fully developed it leaves the host and pupates nearby. Some tachinids lay their eggs on foliage; the larvae are flattened and are called planidia; they remain on the foliage until they find a suitable host.
P.S.  There are currently 9473 letters in our email inbox.

Hello Daniel,
Wow, some hobby! Thanks so much for your attention in this matter.
I apologize for seeming terribly impatient.
Thanks again!
Your help is very much appreciated.
Have a great day.
Joe

Prometheus Moth Caterpillar

Unknown Silkworm with Tramp Stamp
Location:  Suburb North of Atlanta, GA
September 20, 2010 8:40 am
Your site has fed a hidden fire in me for a love of bugs. I commonly find myself crouched over colorful insects snapping pictures or discussing the creature with friends and neighbors…and strangers. :/ My reputation even led to the neighbors walking over Saturday to share their find. My 9yo believes this to be an early luna moth instar but I wasn’t sure if that was the right identification. I couldn’t find any images online that exactly matched this fat green guy. Can you help us? He’s about two inches long. I’ve included pictures of a close up on its ugly light colored face, its front, stumpy and back, sucker legs. So cool by the way! Are the back legs truly suckers or are those fine hairs I think I see that make the legs act like the mouth of a venus fly trap? My 4yo neighbor was just as enthralled as I was watching the back legs open and close. But I ramble…another picture I’ve included is of the awesome tramp stamp mother natur e gave this silkworm…a smiley face on it’s backside. Love it.
Thanks for all you do, bugman. You’ve helped us many, many times and hopefully you can let us know if my 9yo was correct or if this was something completely different.
Update: Looks like I can only include three pics, so I won’t be sending the ugly mug. If you need it for identification, let me know. The legs and tattoo are much more interesting.

Prometheus Moth Caterpillar

Hi Resa,
Your caterpillar is a Spicebush Silkmoth, also known as a Prometheus Moth or Promethea Moth,
Callosamia promethea, which we identified on BugGuideWe got a chuckle when you said you were attaching a closeup of the caterpillar’s head, because your photo is actually its rump.  Then we noticed your update that you were not attaching the head photo.  More information on this lovely moth can be found on BugGuide.

Golden Orbweaver Egg Sacs

Golden Orb Spider
Location:  Hickroy, NC

Dear Bugman,
A few weeks ago you helped identify a Golden Orb Spider for us. We have enjoyed watching it spin and catch it’s prey. We just came back from a camping trip and went to check the back window for our friend. Her web has changed dramatically and there are 2 large brown sacks (each about the size of a large grape) hanging at the corner of the door frame. Would these possibly be egg sacks from our Golden Orb? Any thoughts?

Dear Dlee,
You are correct.  These Egg Sacs were made by your Golden Orbweaver.  She may have died of natural causes or been eaten, or perhaps she just moved away, which explains why her web is no longer maintained.  The eggs will hatch in the spring, and hundreds of spiderlings will balloon off on the wind to be dispersed throughout the area.
