Subject: is this a luna caterpillar?
Geographic location of the bug: Athens, Georgia
Your letter to the bugman: This looks like a luna moth caterpillar but it’s orange, not green ?? Found crawling up my window screen Sept 2017, in wooded suburban-rural area.
How you want your letter signed: curious about color
Dear curious about color,
Many caterpillars change color just prior to pupation. We agree that this is a Luna Moth Caterpillar and it is about to spin a cocoon and pupate. See this BugGuide image.
