Don’t know what he was on. My husband came in from yard work and felt something crawling on his neck! Pretty sure it’s a Geometrid, not sure what one. (NY)
Yes, it is one of the Geometrid caterpillars, but not sure which one…yet….
Geometrid caterpillars have only 2-3 prolegs near the rear ends, instead of the 5 pairs of prolegs found on most other caterpillars. With no prolegs in the middle, they walk in looping fashion, which gives them the look of measuring something…hence the common names of inchworm, measuringworm, loopers, or spanworms.
These caterpillars mostly feed on foliage of woody shrubs or trees. They can ‘stand’ very straight on their hind legs resembling a twig. This makes them very hard to see.
Most of the geometrid moths keep their wings spread out when landing.
Your photo is clear and looks familiar, but have not found which genus or species it is. Will post if I do!
In the mean time, do you have any other photos of different angles you could add to this post?
How long was it? Thx
