Birch Marble

Recorded in small numbers most years, generally from
birch-rich areas in the south and west of the county, and from the Shapwick
area.&nbsp; It may have declined somewhat in
the last century.

Short-barred Marble

There are few records of this species, associated with
sallows.&nbsp; It appears to have declined, as
it was once thinly recorded across the county, but there are very few recent
records.

White-shouldered Marble

Recorded in small numbers most years, from areas where its
foodplant, birch, is common – mostly Exmoor, the Quantocks, the Blackdowns and
the Levels around Shapwick.
