HUGE caterpillar eating grape leaves

Post by DeDeK » Sat, 21 Aug 1999 04:00:00



I have discovered two very gigantic (okay, bigger than a tomato hornworm, but
smaller than a breadbox) caterpillars chewing up my grape leaves.  I searched
my insect I.D. books, but could find no such thing that I saw tonight.
They do resemble a tomato hornworm, bright green, hornworm markings, little
'horn' on their backends, but they're much larger, and it looks like something
pushed their faces in (sorry!  That's the best way I can describe it!).
Does anyone know what it might be?  Or know where I can search to I.D. it?
I'm in zone 7.

Imperial Moth caterpillars.  They turn into very large, bright yellow moths.

DeDe, if these things are already bigger than a hornworm;
call the governor and have him send out the national guard.
Or contact the japanese film industry and make some money
off this critter, but don't face it without backup.

Nope. Imperial Moth larvae are completely covered with silky hairs, and
cannot be mistaken for hornworms. There are several hornworms that will
eat grape, the most common being _Eumorpha vitis_, a larva of which I just
saw today in a small vineyard. The *** sphinx is good-sized and nicely
marked.

Zhan, these things actually made a 'thump' when they hit the driveway!  (when I
threw them at it, of course.  Wouldn't touch the things - I picked the leaf
they were chewing on!)
My grandmother can pick tomato hornworms off the vine and squish them between
her bare fingers.  She backed off on this one.
Maybe I should call godzilla... :)

Thank you for the help.
I had told my mother that I thought I had seen a sphinx moth (from looking at a
book for identification), and after feeding on the flowers of a jimson weed, it
flew over to my grapevines.  
Just out of curiousity, do sphinx moths get misidentified as hummingbirds?  I
thought this moth was a hummingbird, until I saw its antennae.
Thanks again,
DeDe

Ever seen a Hickory Horned Devil (Citheronia regalis)?  Now THAT'S
your nightmare caterpillar!  A good 4 inches long, close to an inch
thick, with 10 segmented, orange horns with black tips on its head.

"Hummingbird moth" is a common name for them.
