fach lygadog / Y Paenog
A very successful species capable of surviving even in sheep rearing districts
provided that some nettle patches are tolerated and thistles and/or other
flowers are available for nectaring. Both nettles and thistles are resistant
to sheep grazing but are intensely disliked by farmers and are becoming less
frequent due to the widespread use of herbicides.
The adult Peacock has an exceptionally long life for a butterfly. Having emerged
from the pupa in late summer, the butterflies feed for the rest of the year,
hibernate, and then lay their eggs the following spring. Some individuals live
on, looking increasingly dowdy, as late as mid June. Thus, some adults may survive
for almost a full year. The larvae are gregarious and are highly conspicuous
on their nettle patches.
