COSEWIC Assessment Summary : Bert’s Predaceous Diving Beetle Sanfilippodytes bertae
Assessment Summary – November 2009
Bert’s Predaceous Diving Beetle
Reason for designation
Despite extensive searches, this Canadian endemic species is known from only two locations in southern Alberta, one of which has been destroyed. It is limited to springs and seepage areas along steep cliff edges or river bends. Its habitat is declining due to trampling by livestock and lowering of the water table due to withdrawals for irrigation.
Designated Endangered in November 2009.
