Moth ID trend

[Psyche]

Ischyja is an interesting genus of large moths.
There are at least seven species in Singapore.

The males can be Ided with some confidence but the females can be very confusing.
Note wingshape is not reliable in fieldshot ID,and it is hard to judge the HW blue band in partially covered shots.
I will follow Holloway's descriptive terms.
