The NBM insect collection includes about 60,000 catalogued collections consisting of an estimated 200,000 insects.  Most are dried and pinned or in envelopes, but there are also significant holdings of wet-preserved odonate larvae.  The collection includes about 7,000 specimens from the 1897-1910 period, originally part of the Natural History Society of New Brunswick Collection (add link), mainly assembled by Dr. William McIntosh (1867-1950; add link), New Brunswick’s first provincial entomologist, and local naturalist A. G. Leavitt (1865-1945). Enveloped vouchers for New  Brunswick and Prince Edward Island from the first Maritime Butterfly Atlas (2010-2015) are housed in the collection. The collection is particularly strong in Odonata of the northeast (New Brunswick, Prince Edward Island, Maine), the work of noted odonatologist and NBM Research Associated Paul-Michael Brunelle (1952-2020), and others.  The collection also has strong holdings of New Brunswick Coleoptera and mosquitoes, the work of NBM Research Associate Dr. Reginald P. Webster. Significant holding of ants and Lepidoptera remain to be databased.
