This is an uncommon hawk moth in our area.
It is some years since I have seen it, and it may not survive in the area for
much longer. The caterpillar looks somewhat similar to that of Smerinthus
cerisyi, but its skin is markedly granular, it has irregular reddish
spots on it, and it is to be found on rosaceous shrubs such as Ocean Spray Holodiscus
discolor, Hardhack Spiraea douglasii and Ninebark Physocarpus
