Don't ask me how come I was reading the Wikipedia page on pests that feed on Maple trees. (Something to do with looking up sycamore species, I think.) But I did, and I learn that one such pest is a moth called Setaceous Hebrew character.
I thought it was called that because Wikipedia couldn't print the Hebrew character in question, but it could. It's a "nun". It's just the insect is called Setaceous Hebrew character.
Coolest insect name out there, I believe.
