Larvae found under the bark of birches on heaths and in light woodland.
Attracted to the MYO and CUL pheromone lures, usually in the afternoon.
Red-belted, myopaeformis, can be on the wing in May and also responds to the CUL lure so it cannot be assumed that insects coming to that lure in May are Large Red-belted. Insects will need to be inspected carefully.
Retained Specimen / Photograph will be Required.
