Caithness Moths - Common Heath

[Pterodroma]

http://forum.caithness.org/picture.php?albumid=83&pictureid=859

As its name suggests the Common Heath is a common moth on moorland where its larvae feed on a variety of heather species. It is on the wing from May through to June, with a small second generation in August. It is active by day and can be seen flying over heather like a small butterfly. The large feathery antennae of the male, as in this picture, distinguishes it from any butterfly. It over winters as a pupa in a cocoon on or just below ground.

R these being caught?

[Pterodroma]

Yes, they are being caught, photographed and released unharmed at the catching site.

This one was caught in a net as it was flying in the day, but I also use light traps and some other methods, none of which cause harm to the moths.

Just curiousity many pepper moths and what colour? early 80s study of them

[Pterodroma]

Peppered Moth has not been recorded in Caithness since 1975 - possibly because of lack of field work in the optimum habitat.

Prior to 1975 it was said to be found only on birch around Berriedale - I have no information on which colour morph predominated.

It should be an interesting time for any one to study moths over the next few years to measure the effects of atmospheric pollutants (Iceland) has on the levels of enzymic activity and colour along with the possible temperature influence that often follow large discharges of ash.

Well that's another species identified, saw that moth last week, but it did n't hang about long enough to get a picture.
