Aplocera efformata, the lesser treble-bar, is a moth of the family Geometridae.

It is best distinguished from this that the innermost of the wing's three dark cross-bands are fairly straight with a marked bend near the front edge, not evenly curved.

the outermost cross band has two, more or less marked triangular projections on the outer side.

At the wing tip there is a short, slightly diffuse, brownish slash.

See Townsend et al.[1] There are two to three generations per year with adults on wing from the end of April to mid-November.
