Can anyone tell me the most likely species of insect to use the edible chestnut
as a larval substrate?  Would this be latitude dependent?

Greetings Diamondjack,
I base my answer on the number of instances I found an insect name
mentioned along with sweet chestnut on the Internet. It appears that
the most common insect to use the sweet chestnut is the silkmoth, and
various species of silkmoth and other moths are mentioned. It is hard
to tell what exactly what subspecies of the silkmoth is more common
only on the sweet chestnut. The Chestnut weevil is mentioned below,
but I think it attacks another kind of chestnut, the American
Chestnut, rather than the Sweet Chestnut. I also do not think it is
latitude dependent.

The raising of Dictyoploca simla [SIMLA SILKMOTH] by Neil West.
- "The larvae will take Hawthorn [Crataegus], Oak [Qercus] and Sweet
Chestnut [Castanea], but best of all is Walnut [Juglens]."

Foliar Chemistry and Gypsy Moth, Lymantria dispar (L.), Herbivory
on Pure American Chestnut, Castanea dentata (Fam: Fagaceae),
and a Disease-Resistant Hybrid (Adobe PDF Document)
- This is an instance of another moth whose larvae feed on chestnuts,
though not necessarily the sweet chestnut.

- Mentions gypsy moth as a parasite of Sweet chestnut. (clicking on

- Oaks (Quercus spp.) are preferred; however, it can also be found on
beech (Fagus sylvatica), sweet chestnut (Castanea sativa), birches
(Betula), hawthorns (Crataegus), hornbeams (Carpinus), Prunus and
several other trees and shrubs.
