Sussex Emerald Moth
The Sussex Emerald moth is one of Britain's rarest moths.
It is confined to a single site in the South of England. There
it mainly uses wild carrot as a foodplant but ragwort is sometimes
used as a secondary food. It flies in July and August.
It is a good
illustration of the fact that an insect may be rare even though its
foodplant is common Wild Carrot like Ragwort is not a scarce plant
yet this creature is extremely scarce and vulnerable. There are many
ecological factors which affect the occurrence
of any given species. Species may be rare even though their habitat seems common.
