Toe Biter?
Not sure but I guess its a Toe Biter.All the pics I saw didn’t have any eggs so Im sending you this cool pic. Found it in a pond in Gulfport Mississippi.

Hi David,
This is a Predatory Water Bug and it has many of the same common names as the more commonly photographed genus Lethocerus, including Giant Water Bug, Electric Light Bug and Toe-Biter. This is however a different genus, Belostoma. Males of this genus carry the eggs which the female cements onto his back.

ID caterpillar
I’ve looked at all your caterpillar photos and don’t find this guy. What is it? It is on a bluebonnet (Lupinus texensis.)

Hi Beth,
This is just a guess. We did a web search of caterpillar and lupine and found numerous postings regarding the returning lupine population being ravaged by caterpillars after the eruption of Mt Saint Helens. Though we could not locate a photo of this caterpillar, the description reads: “Much of the lupine damage was attributable to caterpillars of Filatima sp. moths, herbivores that feed on the lupine. The caterpillar ties lupine leaves together in silken masses to feed on the green tissue, dramatically reducing the number of seeds produced by lupines and, consequently, the rate at which the lupine population can expand.” This is consistant with your image that seems to show the silken mass on the leaves. We then tried BugGuide, but could not locate the genus, only the family Gelechioidea, and the Family Gelechiidae, Twirler Moths. Still not images of caterpillars that match yours. Perhaps one of our readers can find the answer.

Update: Caterpillar on Lupine: Twirler Moth Caterpillar??? (05/18/2007) ID caterpillar In regards to your posted photo, it looks like the caterpillar may be Pyralidae family, species: Uresiphita reversalis, which I have on my own website,

A further identification for you
Hey there! Love the site. I noticed on your main page that Cheryl from British Columbia sent you images of lace bugs and a mystery ground beetle. Her beetle looks remarkably to me like a specimen I snapped a shot of last week on the other side of the country, just north of Toronto, Ontario. I think her mystery beetle is Carabus granulatus, an introduced species from Europe. Here’s a link to my picture as posted on

Hi Dave,
Thanks for the correction and also thank you for providing an image of a living specimen of the Granulated Ground Beetle.

crusty the bug
Any information regarding this specimen would be much appreciated. I found the little guy in my basement. At first I thought it was a small spider (it moved like a spider as well). It also rights itself when on it’s back similar to a crayfish of lobster. Weird little thing eh Thanks for your time,
Dave from Winnipeg, Canada

Hi Dave,
This is a Masked Bedbug Hunter, one of the Assassin Bugs. Immature Masked Hunters are sticky and all manner of lint sticks to them and masks them.

parnassian instar
Hello Daniel,
Here are some pics of the earlier instar. I apologize that they are a little out of focus. I was having trouble with my camera at the time & had to send it in for repairs soon after. I will also send a few more in separate emails as we have had some problems with our server lately, if you send more than two at a time they disappear into cyberspace. … The Parnassian was found in Well County North Dakota. I cannot remember what year though. I am thinking it was around 2003-2004? I can look for my records if you need to know. It was also found in town & feeding on Dill & Parsley. This set pictures are of the instar just before the last.

Hi again Misty,
First, we really want to thank you for identifying an earlier Parnassian Caterpillar that we had misidentified on our site back in 2006. We are also thrilled to get your photos of both the earlier striped caterpillar instar and the final spotted instar. In an attempt to not add any more confusion, here is what we do know. Parnassian is the common name for all butterflies in the genus Parnassius. In Europe, this same genus is known as the Apollo Butterflies. The genus Parnassius is found in mountainous areas of the northern hemisphere where there are snowy winters. There are several North American species. Neither Parnassius clodius, nor Parnassius phoebus are listed as living in North Dakota in our Butterflies Through Binoculars (the West) book and P. clodius has the more western range. There is much variability in the adult coloration, which complicates identifications. BugGuide lists another species, Parnassius smintheus, the Rocky Mountain Parnassius that ranges “From New Mexico north along the Rocky Mountains and into southwest Alaska.” All that said, we are eager to get your update from the expert on the proper species identification of your specimen. Thank you so much for adding to the information on our site.

Caterpillar Identifications

The original ID of Cucullia intermedia (2006/01/20/probably-parnassus-butterfly-caterpillar-not- hooded-owlet-moth-caterpillar/ ) is probably correct, although moth caterpillars are not my area of expertise. In any case, these are not Parnassius larvae, which have fine black hairs (making them look somewhat velvety), all instars similar in appearance (black with rows of light spots), and feed on Sedum or Dicentra (not dill or parsley) locally. Please see this Parnassius smintheus from Idaho: . North American Parnassian cats are rarely encountered, so a number of Internet photos are regrettably misidentified (such as ).
I hope the above information is helpful.
Best wishes,
