Our summer fundraiser has arrived, and we need your help!
We depend on donations to keep Butterflies and Moths of North America online and free. If everyone who uses this resource makes a donation, we could cover our ongoing costs, develop new features, upgrade the system, and maybe even remove those pesky ads. Please make a one-time or recurring donation to show your support for this valuable source of information. Thank you!

Coordinator notes: I don't think Cycnia oregonensis has any spots on the wings. It would also have a yellow head, which can't be seen well enough here. This is likely either Spilosoma congrua or S. virginica. The former has an all-white abdomen while the latter has lines of alternating black and yellow spots down the abdomen.
