Eurys laetus (Pergidae:Euryinae) PW082
Workbook
Note: This is a “work in progress”. Changes may be made as I discover additional relevant information.
Detailed images of an adult female Eurys laetus (PW082) collected by James Peake at Mt. Buller, VIC on 23/12/2025 (see this iNaturalist observation).
Images of the living insect taken by James are followed by shots of the pinned specimen.
Notes accompanying these images were taken from the original description by Westwood (1842, 1880) and revisions by Morice (1919) and Benson (1934). I have noted in square brackets [] where features of this insect differ from information in the literature.
