yesterday I observed a hummingbird moth (plump body, rust and pale olive colouring) laying single pale green eggs on the base of the trunk of a small Nannyberry Viburnum. Are viburnums potential hosts for this moth? I read on this site that they eat honeysuckle, and that Bumblebee moths eat viburnums, but I am certain this was a hummingbird moth, as I was able to have a very good look at it.
Could it be that viburnums are also host plant options for them, just like some swallowtails eat both parsley and rue.
The site actually says, "honeysuckle family," which includes the viburnums. The Hummingbird Moth larva also eats hawthorns and plums, which are in the rose family.
