Your letter to the bugman: I don’t have a clue, but it’s about as big as the orb-spinning house spider, and orange for halloween! Descended on silk from a tree. Is that an egg sac, or an abdomen?
How you want your letter signed: LH
We don’t know if you are serious about your subject line, but this does appear to be a Pumpkin Spider, which is how the orange color variation of the Marbled Orbweaver, Araneus marmoreus, is often called. Though the Pumpkin Spider was already our Bug of the Month for December 2013, we feel that enough time has passed to honor it again, so your submission will be featured as our Bug of the Month for November 2018. Like other Orbweavers, though there is a possibility that a large individual might inflict a bite, the Marbled Orbweaver is considered harmless. The large abdomen of this female indicates she might still have to produce an egg sac or two before winter.
Thanks so much!
I’m interested in what type of webs it spins- the usual big bullseye?
This one was inside for a few days!
Yes, they build a similar orb web. The color variation is not seasonal, but the spiders mature and become noticeable in the fall. The hatchling spiders that emerge in the spring are very tiny and easy to overlook.
