Moth trapping for 'river flies'

摘要

Our recent initiative through the YNU Freshwater Section is to encourage Lepidoptera recorders and others to record adult mayflies (Ephemeroptera - E), stoneflies (Plecoptera - P) and caddisfiies, also referred to as sedges or sedge flies (Trichoptera - T) from their light trap 'by-catch'. Thus the acronym EPT, used in this article, refers to these three groups collectively.
