Separation of Halpe wantona and arcuata

[Psyche]

It is nearly impossible to ID Halpe from a single view.

1 looks to be H. wantona as by comparing the field shots below.

The FW is lowered too much & so there is no way of knowing a cellspot is present.

2 looks like H. arcuata but the subapical spots are distinctly yellow.

H. veluvana is the species where the FW spots are stated to be yellow.

Both H. arcuata & veluvana have spots 2 & 3 widely overlapping.
H. veluvana always have a FW cellspot & H. arcuata almost never.

Many thanks for the feedback. General indictors are fine, as, as you say, single photos are so difficult.
