I looked through your lady beetle archives until I was afraid I wouldn’t be able to sleep tonight, trying to identify this beetle in Southcentral Alaska. Same size as the famous ladybugs we all know, but an entirely different pattern.
This is not a Lady Beetle. It is a Leaf Beetle in the family Chrysomelidae. We do not receive many identification requests from Alaska, and we always enjoy trying to identify insects from the far north. We identified your Leaf Beetle as Chrysomela falsa thanks to this BugGuide image, but alas, other than providing data that there are sightings in Alaska and the Northwest Territories, BugGuide does not provide any information. Of the subgenus, BugGuide does note: “hosts: willows, poplars (Salicaceae), alder (Betulaceae).” We hope we have restored your ability to sleep.
