The section of the canal between the Wharf and the Grundon Hide produced a good selection of invertebrates this morning, including several Orange-tip butterflies. Smaller species included leaf mines of Celypha woodiana on Mistletoe, galls of the mite Cecidophyes rouhollahi in Goosegrass and a number of Iris Flea Beetles (Aphthona nonstriata) . Celypha woodiana is something of a Gloucestershire speciality and is a BAP species.
