Heringia senilis Sack, 1938
Biology & ecology:
This species is reported to have been bred from the galls formed in Poplar Populus leaf petioles as a result of the aphid Pemphigus populitransversus. Adults are rarely reported and seem to be more readily recorded by breeding from larvae in poplar leaf galls.
There is a scatter of records that do not fully reflect the known distribution of this species. We know of records from London and from Peterborough but have not got the records as yet.
Status & conservation:
The frequency of recording and range change shown are for the aggregate of H. heringi and H. senilis.
