Orig. Comb: Coccinella venusta Melsheimer, 1847

(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.)
Remarks
Neoharmonia venusta is variable, so much so that just going by the pronotal spot-pattern, the spmn in the middle row below could initially be mistaken for Harmonia axyridis (Asian Lady Beetle)
See Also
The other subspecies,
Neoharmonia venusta ampla, occurs in the southwestern U.S. and Texas, with very little range overlap.
