Entomology (Study of Bugs)/Type of Bug


My brother-in-law found this bug on the hood of his car.  Not sure what it is and wanted to find out from someone who might know something about it.  I am attaching a photo of this bug

Hi, Donna:

Thank you for including the image.  No question what it is....

That is an "Ailanthus Webworm" moth.  Here is more about it:


Not all moths are drab and dull.  Not all moths are active at night.  Surprise!

Hope this helps.  Thanks for sharing the find!

I answer insect and spider identification questions ONLY. Attach images if possible. No "what bit me?", "what do I feed this bug in captivity?", or science fair project questions please. NO TECHNICAL QUESTIONS ABOUT INSECT PHYSIOLOGY.
