Rare Bee Rediscovered After 119 Years
30 Mar
Summary
- Chestnut mining bee found in New York after over a century.
- Discovery highlights success of urban habitat restoration efforts.
- Citizen science is crucial for finding lost or rare insect species.

A significant rediscovery has been made in New York State: the chestnut mining bee (Andrena rehni). This species had not been recorded in the region for 119 years, with its last confirmed sighting dating back to 1904. Its reappearance in a Syracuse urban orchard indicates that conservation efforts aimed at restoring chestnut trees, which are vital for the bee's sustenance, are proving effective.
The discovery was made by an entomologist who, despite the urban setting, had a hunch the bee might be present. The bee's presence in a densely populated city surrounded by highways challenges the notion that only pristine habitats can harbor rare species. This success also highlights the growing importance of citizen science in tracking down rare insects.
Globally, there is an increasing effort to find 'lost bees' – species documented in museums but not seen in decades. The chestnut mining bee is considered a 'holy grail' in this context. Its rediscovery offers a beacon of hope, proving that dedicated searching and habitat restoration can bring species back from the brink.
