Moved - please don't Frass
Moved from ID Request.

Nobody Frass this, please, I'm collecting seasonal data for how late in the year H. axyridis larvae are active outdoors. This is the latest I've seen one in New England.

double-branched "spines" are the key
From the moment they hatch, H. axyridis larvae have these distinctive double-branched "spines" - unique among North American lady beetle species. You do need a magnifying glass to see them on the hatchlings, though!

The pattern of the larvae changes as they develop - black at egg hatch, getting a little more orange at each of the three molts, until they look like this one. This is the final larval stage, then it will pupate - usually the pupa can also be identified by the double-branched spines of the shed larval "skin" stuck to the back.


I'm curious about whether it will emerge as an adult now, or if the pupa overwinters at all. H. axyridis adults are notoriously alive and home-invading in the fall, but I don't know how much cold weather the larvae and pupae can survive.
