The genitalia slide collection of Prof. John G. Franclemont comprises 8800 Canada balsam mounts that were prepared over the course of his career. The first slide was dated 7 December 1935, and the last slide was prepared 26 October 1994. The early slides are archivally labeled, however the later slides have only a wax pencil legend including slide number, taxon name, and date of preparation. The associated PDF lists all the taxa alphabetically. If you would like to borrow any of this material, please contact us through the email page, and we will make certain the slides are fully labeled. We can also photograph a moderate number of slides, should that prove a means to keep the slides safe from mail travel. Our plan is to ultimately have this invaluable overview of noctuoid genitalic preparations available on this website.
Prof. Franclemont also reared the larval stages of many lepidopterans from eggs derived from captive females. These alcohol-preserved larvae are associated with their mothers preserved in the Franclemont pinned material. Mr. Jeffry Petracca, Cornell B.S. Entomology 2011, stabilized the Franclemont larval collection, and has compiled the list of taxa also to the right. We have also digitized 1033 images of caterpillars from Kodachrome slides taken by Prof. Franclemont during his rearings of eggs laid by single females. These images are available in a searchable collection in the Insect Image Gallery. Thus for some species, we have individual series with preserved larvae, photographed larvae, genitalic dissections of both males and females, and spread adults. We hold numerous other larval Lepidoptera derived from W.T.M. Forbes. Contact the collection manager, Dr. Jason Dombroskie, for information on possible holdings of a taxon of interest.
