Celastrina ladon versus neglecta
































The criteria for evaluating male Celastrina is the DFW intervenous area (between veins).
For instance:

NEGLECTA
Androconia (small white pheromone scale) - Present
Long transparent overlying scale - Absent
LADON
Androconia (small white pheromone scale) - Absent
Long transparent overlying scale - Present
