Lady Beetles are adored by many and who can blame them – their bright patterns captivate the eyes and their reputation as pest predators make them a friend to farmers and gardeners. Many of us are familiar with the nonnative Asian Lady Beetle, but did you know that 36 native lady beetle species have been historically documented in Vermont? Unfortunately, 12 of these species have not been seen since the 1970's. It's a mystery we're eager to solve!
What has happened to these beetles? Are they completely gone? It's hard to know for sure without more surveys across the landscape. Scientists thought that both the Two-spotted and Nine-spotted lady beetles were extinct in New York until citizen scientists directed by the Cornell Lost Ladybug Project rediscovered them. Here at VAL, we're on a quest for similar information.

Mysterious disappearances
Lady Beetles weren’t on our radar until we unearthed a 50 year old document – Lady Beetles: A Checklist of the Coccinellidae of Vermont. Within its pages, the authors noted the first and last date each Lady Beetle species was collected in Vermont and the total number of specimens known. This data showed that native species previously considered common across the state were now rare or even missing. Alarm bells started going off and we knew that this puzzle needed answers.
