The Lancashire & Cheshire Entomological Society was founded in 1877, in order to facilitate the furtherance of the study of entomology by amateurs and professionals alike, its activities centred upon Lancashire, Cheshire and adjoining parts of North Wales. The Society originally held its Indoor Meetings at Liverpool Museum, though more recently (as of the year 2000), the Society has held its Indoor Meetings at Frodsham Community Centre.
The Society aims to promote the study and conservation of invertebrate fauna, again centred geographically upon Lancashire, Cheshire and adjoining parts of North Wales, all areas containing active members. The Society's activities include monthly Indoor Meetings, held from October through to the following April, and assorted outdoor events during the Spring and Summer months. Active members participate in events such as Bio-Blitzes, entomological recording, and the recording of other invertebrate groups of interest.
