Didea intermedia Loew, 1854
Biology & ecology:
The larva is strongly associated with Pinus. Adults are almost always associated with coniferous forest, including conifers planted on sand dunes. A few records from deciduous woodland in southern Britain are suspect, and may well be misidentifications of D. fasciata. Adults are flower visitors and can be found at yellow composites. In Scottish pinewoods they can often be found visiting White Bedstraw Galium saxatile, sometimes in considerable numbers.
A northern species, with most records from Scotland and north-west England. It occurs on coniferised heathland on the Surrey/Hampshire border, and on the heathlands of Dorset and Hampshire.
Status & conservation:
There has been no significant change in occurrence over the past 25 years.
