One of two North American subspecies of Neoharmonia venusta.
mostly: May-Aug (BG data)
Soft-bodied insects and larvae; perhaps scale insects. (2)
Per Whitehead & Duffield (1982), they are "major predators of larvae and pupae of the willow leaf beetle Plagiodera versicolora (Laicharteg) in the mid-Atlantic region of the United States."
Were coll. in central Texas on willows (Salix) infested with Chrysomela texana (Schaeffer) which they may have been feeding on (MAQ, pers. obs.)
The other subspecies, Neoharmonia venusta ampla
, occurs in the southwestern U.S. and Texas, with very little range overlap.
