Conservation Issues
None here. The species is a summer migrant from southern Europe,
and does not survive winters in Britain and northern Europe.
|
Flight PeriodMigrations start quite early in the summer, but the species is most often seen in late July and August, when the next generation emerges here. A further generation results in some sightings later in the autumn.
DistributionClouded Yellows may be seen almost anywhere, but in most years only a few are recorded in Gloucestershire. 1998 was a better year than average with over 20 sightings reported. 1996 was a particularly good year with 78 records.
