280 days of Urbpandemonium #124

You would be forgiven if you thought this little orange and white moth had a bit of a tropical look to it. In fact, it's thought to native to Florida and points south, its caterpillar feeding on a tropical plant called a paradise tree. So what is it doing in the temperate urban forest of Boston? It turns out that another plant, the tree-of-heaven Ailanthus altissima, is suitable food. That turns out to be great luck for the moth now called the Ailanthus webworm Atteva aurea* since the tree-of-heaven is an invasive urban dweller that cracks sidewalks and colonizes vacant lots. The moth can't tolerate our nasty winters, and so migrates up from Florida each summer.



*Atteva = Origin unclear. Speculation: perhaps from Modern English (though obsolete, and dialectical) atter, that from Old English aettor poison, pus, plus Greek suffix eu (or ev) good, well, with an adjectival ending -a. (English atter poison is not related to adder, the snake, incidentally.) This seems semi-plausible, given that the author of the genus was English. Aurea means "golden."

Do you guys know each other? You both live in the NYC area, so you've probably met.

Bahaha! I...what?

She doesn't look familiar. Unless she goes to puzzle events or board game meetups or she works in a retail food store, it's unlikely we would know each other. (Of course you're joking, but just in case, I answered.)
