World-renowned butterfly and moth expert and author David Brown leads a week of field trips, workshops and lectures focusing on rare and interesting summer butterflies and moths of Somerset.

“I enjoyed seeing species that were new to me but also meeting like minded people. David Brown is very knowledgeable and willing to give every assistance. Halsway is a lovely venue with good food, accommodation and friendly staff.” Participant

This course provides an opportunity to view some of Great Britain’s rarest butterflies. Each year, different target species are chosen as a focus for field trips, learning about their life cycles and fascinating habits.

Light traps will be operated in the wooded grounds of Halsway Manor where it is possible to see up to 100 species of moth during the week including specialties Brussels Lace, Cream-spot Tiger, Lead Belle and Ruddy Carpet. Illustrated evening talks and workshops will help sharpen identification skills and provide knowledge on the ecology of selected species.

Participants may be asked to car-share to help with transport on field visits.
