Lappet Moth Caterpillar

Dear Sky,
This is not a Stinging Slug Caterpillar.  We believe it is a Lappet Moth Caterpillar in the family Lasiocampidae, possibly the American Lappet Moth which is pictured on BugGuide.  According to BugGuide:  “Caterpillars feed on leaves of alder, birch, oak, poplar, willow, snowbrush (Ceanothus velutinus), chinquapin (Chrysolepis chrysophylla), and members of the rose family; larvae rest longitudinally along a twig during the day, and feed at night.”

Thanks for getting back so quick! I hate to question the experts,but are you sure? Because the lappet moth pics look fairly round, although the coloring sure  is similar in some! and you can see feet if you look closely thru the hairs, this thing is weirdly flat and kinda ‘suctioned’ on to the 2by 4

Do you have an image that shows the entire caterpillar?  Your image is cropped and we cannot tell how much of the caterpillar’s body was outside of the edge of the frame.  We do not understand your statement “Because the lappet moth pics look fairly round.”  This image from BugGuide illustrates a Lappet Moth caterpillar at least six times longer than it is wide, and that is not “round”.

Milkweed Tussock Moth Caterpillar

Dear Jeff,
This is a Milkweed Tussock Moth Caterpillar and it poses no threat to humans unlike other caterpillars that are known to sting.  Insects that feed on milkweed are able to incorporate toxins which make them distasteful or possibly even toxic to predators that eat them.

Saddleback Caterpillar

Dear Vickie,
This is a Saddleback Caterpillar and we did not know they feed on bird of paradise.  According to BugGuide they feed on:  “
Many trees, shrubs, and grasses including apple, asters, blueberries, citrus, corn, dogwoods, elms, grapes, linden, maples, oaks, Prunus species, sunflowers and viburnums. Troy has personally seen them feeding on liriope, cherry, oak, and holly.”  Handle with caution.  The Saddleback Caterpillar has stinging spines.

Cecrops Eyed Silkmoth Caterpillar

Dear Urbanohno,
What a marvelous find.  These are caterpillars of the Cecrops Eyed Silkmoth which we identified on BugGuide.  According to BugGuide:  “Adults in spring. Eggs are laid in rings on twigs of host plant. Early instar larvae are gregarious and feed in large groups, but they spread out and become solitary in later instars. Larvae are present in summer to early autumn. Overwinter as pupae in cocoons woven among (or incorporating) vegetation, mostly leaf litter on ground, sometimes on plants.”

Ah so – Thank You very much Daniel!
