Callicera spinolae Rondani, 1844
Biology & ecology:
The larvae inhabits rot-holes and have been found in Beech Fagus, Horse Chestnut Aesculus hippocastaneum and Field Maple Acer campestris, and Poplar Populus sp. (Russian record). Trees bearing suitable rot-holes are not necessarily large or ancient. Larvae have also been found in heart rot extending a long way into the tree, potentially making them more difficult to find than other Callicera larvae. This is a species which has a tendency to turn up at new sites for a period of years and then disappear again, suggesting ready mobility and transient populations.
This species is confined to East Anglia, with recent records from Cambridgeshire, Essex, Hertfordshire and Suffolk. Most records for Norfolk and Suffolk are old, although there is a 2007 record from Winterton in Norfolk.
Status & conservation:
Records are sporadic, but there is no evidence of any particular trend.
