Genitalia
Males: the genitalia of males Macaria alternata and Macaria notata are almost indistinguishable. On M. alternata, the sacculus is stated to be slightly more protruding than on Macaria notata, but this should not be regarded as diagnostic, however examination of the eighth sternite is usually sufficient for ID.
Eight sternite deeply cleft, lobes set close together.
Females: Bursa copulatrix twice or three times lenght of ductus bursae.

Hibernates as pupa in a cocoon underground.
The adults are active from dusk and later come to light.
