Here's an example, submitted by Ian Wallace:
Museum insect collections are full of human interest vignettes as well as the actual collections. Among those at World Museum Liverpool are a giant wood wasp, which sports an impressive egg-laying spike that a member of the public handed in during the 2nd World War thinking it was a secret weapon dropped by a German plane. Also along the war-time theme is a Scarce Swallowtail Buterfly with a few holes in the wings that the collector, Colonel J.A. Graham notes on the label “Jeancourt June 1917 blown up by a 3″ shell and picked up half dead”.
