Erionota torus torus ???

[Silverstreak]

Went back and collected 3 pupae.....they all eclosed this morning

You might be right, , both species might be on the same hostplant at the same time...... out of 3 eclosed, one is smaller and having a straight termen, the other two with convex termen.

Can it be 2 coincidences of both species on the same plant and eclosing at the same time???

May be we should consider investigating the genitalia of the smaller individual with straight termen to verify if it is a E. thrax or a E. torus????

No need if you have the specimen or upperside view.

In Erionota thrax
1. The forewing apex is slightly whitened along the edge.( not so in E. torus.)
2. The small spot in space 3 is usually more or less triangular (quadrate or squarish in E. torus. )
3. The big spot in space 2 have its outer/inner margins straight or convex.( one or both margins indented in E. torus. )
