Observation notes: The caterpillar in the picture was found wandering on a metal barrel under maple trees in August 2017. After taking pictures it was transferred to a glass container for identification. Maple leaves were placed in the container as well. By morning the caterpillar had wrapped itself in the leaves and spun a cocoon around itself attaching both the leaves and the cocoon to the glass container. Several days later a "flask" shaped cocoon was found on a Madrone tree. The cocoon in the glass container and the one in the tree seem to be of the same Ceanothos relatives. It is March 2018 now and both cocoons are being watched closely.

Coordinator notes: This is the most likely ID, but note that H. gloveri has also been found rarely in this region.
