The Museum collection includes over one million pinned specimens and numerous microscopic preparations. There are over 500 publications on these collections, summarised in the bibliographies detailed below.

There are an estimated 12,000 species of insect in Ireland, possibly many more. Species new to Ireland are recorded every year, some are new arrivals, others may have been overlooked before.
