Waved Sphinx Caterpillar

Hi Crystal,
According to Bill Oehlke’s website Sphingidae of the Americas, the caterpillar of the Waved Sphinx,
Ceratomia undulosa, changes color:  “Just prior to pupation, larvae frequently take on a rosy hue.”  Sphinx Moth caterpillars are often called Hornworms because of the prominent caudal horn found on the caterpillar of many species, including the Waved Sphinx.

Beetle with big pinchers?

Hi! Found this beetle in a parking lot in Winnipeg, Manitoba around midnight around Sept. 19th. It was about 10oC or 50oF, and there were about 50 of the same bugs all over the lot. Wondering if you could identify it for me? Thanks!

Hi Emily,
The Giant Water Bug or Toe-Biter is one of our most common identification requests, and it seems we must have close to 100 images of Toe-Biters posted to our site.  People frequently mistake this True Bug for a beetle.  We like to post a new image of a Toe-Biter  every once in awhile.

Hi Daniel,
Sorry I didn’t provide more details.
The congregation of moths was all over the old Spanish fortress, on the walls, the ground, everywhere! Even inside open rooms. No trees anywhere near, and very little other vegetation.
I’m attaching a photo of what I believe is a white witch, and one of a section of wall about 1 sq meter, where I counted at least 10 moths.

Owl Moth

Hi again Ben,
We are sad to inform you that this interesting white moth is NOT a White Witch which is the largest moth in the world if the measurement is determined by wingspan.  We believe this is a smaller relative in the same genus, the Owl Moth,
Thysania zenobia, which we identified on the Moth Photographers Group website and then matched it on BugGuide.

Snakefly Larva

Hi Michael,
This is a Beetle Larva, but we are not certain what family it belongs to.  We often have trouble with the identification of larval stages.  We will contact Eric Eaton for assistance.

Correction thanks to Eric Eaton
I can appreciate your hectic life.  I have much the same situation here, and not liking it much…..
Congrats on the book!  Let me know how I can help crank up those sales…..
Well, it is not a beetle larva for one thing.  At least, I’m pretty sure this is the larva of a snakefly, order Raphidioptera:
Easy mistake to make, and it took repeated encounters before I learned the difference, too.

Can you please identify this ”bug”? I noticed this guy on my fathers deck about a 5 weeks ago. He is about as big as your thumb, and was waving his ”head” about when first noticed.

Tiger Swallowtail Caterpillar

Hi Dan,
This is the Caterpillar of a Tiger Swallowtail, though we cannot say for certain if it is a Canadian Tiger Swallowtail,
Papilio canadensis, which is well documented on BugGuide, or the Eastern Tiger Swallowtail, Papilio glaucus, also depicted on BugGuide, as the ranges of the two species overlap and they look quite similar.  Both species have green caterpillars that turn orange or brown and leave the trees where they have been feeding as they prepare to pupate.

Hello! Could you please identify this bug. Would be happy to know the scientific name and common name of this bug.

Root Borer from the Philippines

Dear anyway,
Your photo is quite blurry, which would have probably made any conclusive identification impossible, but luckily, we received another letter from the Philippines today with correctly focused images of what we believe to be a Prionid Root Borer
Ziglipton sanchezi, probably the same beetle you submitted.
