Whitemarked Tussock Moth Caterpillar

Whitemarked Tussock Moth Caterpillar

Dear L Adair,
This is most likely a Whitemarked Tussock Moth Caterpillar,
Orgyia leucostigma, but we would not rule out that it is a different species in a genus that has many similar looking caterpillars.  You should warn any young children to avoid handling Whitemarked Tussock Moth Caterpillars because, according to BugGuide:  “CAUTION: Avoid handling the caterpillar, as its hair is known to cause allergic reactions, especially in areas of the body with sensitive skin (e.g. back, stomach, inner arms). Seek medical treatment if a severe reaction occurs.”

Lappet Moth Caterpillar

Lappet Moth Caterpillar

Dear Delores,
This is definitely a Lappet Moth Caterpillar in the family Lasiocampidae, but we cannot say for certain which species or even definitively which genus.  According to a posting entitled Living Illusions on the Lappet Moth 
Phyllodesma americana on the Beautiful Nightmares blog:  “The caterpillars munch on leaves by night, hiding on twigs and bark by day. They are also well-hidden, but because they have to be able to live on a variety of different trees, each of which has a differently-colored bark, lappet caterpillars don’t have a color that matches a particular background. Instead they, like their parent moths, have bodies with distorted outlines, specifically a lateral fringe of long hairs.  On bark, this helps a caterpillar “merge” with the bark on which it rests. …  Animals that depend on camouflage have to stay very still to avoid detection, but if they are spotted, staying still quickly becomes futile. Many animals use color to startle predators as a backup plan, the best-known example being the red-eyed tree frog. At rest, the frogs appear a solid leafy-green, but if disturbed, they quickly open their eyes. The sudden appearance of two giant, bright red eyes can be enough to startle a predator, which might give the frog time enough to make a hasty escape.”  Discover Life has images that support that might be a correct species identification, however, based on this BugGuide image, we would not rule out that it might be in the genus Tolype.  At any rate, your marvelous images clearly depict both the camouflage and the flash of warning colors.

Thank you Daniel for identifying the Lappet moth caterpillar.  I searched high and low trying to identify it myself and finally gave up.  Again, many thanks.

Found this little fuzzy “thing” on the backside of a leaf on my River Birch tree. Never have seen anything like this before so would like to know exactly what it is. Can you help?

Dear Rick,
You can see by comparing your caterpillar to the one in this BugGuide image that this is a Whitemarked Tussock Moth Caterpillar,
Orgyia leucostigma.  According to BugGuide:  “CAUTION: Contact with hairs may cause an allergic reaction.”

Dear Peter,
We agree that this is a Lappet Moth Caterpillar in the family Lasiocampidae, and there is a matching image on iSpot, but it is only identified to the family level.  It appears like it might be the same species or a closely related species to this Indian Lappet Moth Caterpillar.

Found at Fundacion Los Monos y Selva Vida near Puyo, Ecuador on June 26.
After searching many times using various keywords to describe the caterpillar I came up short. I found a stock photo with a similar one that I have in my picture, however, they do not supply a species and only say “A caterpillar perched on a branch in the Tandayapa Valley of Ecuador.”
What kind of butterfly or moth do you think it will turn into?

Dear Ryan,
This reminds us of a Lappet Moth Caterpillar from the family Lasiocampidae, but we have not had any luck matching your image to any identified species.  Interestingly, while searching, we also found the “caterpillar perched on a branch in the Tandayapa Valley of Ecuador” you mentioned.  Once again, we would refer you to Cesar Crash at Insetologia as he can search the internet in Portuguese and possibly Spanish.
