Macrophya duodecimpunctata Linnaeus, 1758

Meise ● Belgium

Description: Black body, with cream-whitish marks. It has long legs and antennas. The wings are brown. Size: 10-12mm.

Biology: The adults fly in summer. Food plants: Cyperaceae and Gramineae.
Adults of M. duodecimpunctata are particularly attracted to Alnus, which was stated to be a host in some earlier sawfly literature. Egg-laying on Alnus by M. duodecimpunctata was thought to have been observed by Chambers (1947).

Distribution: Widespread and locally abundant Palaearctic species, recorded in most European countries including southern Sweden and Norway (Taeger et al. 2006).
