My friend, Line Sabroe had made a way to distinguish between Phigalia pilosaria and Apocheima hispidaria.
Maybe other knew it, but I have never "seen" this before.
You can find something alike by Porter.
* If the warts dorsally, on segm 4-6 (especially 5-6) is substantial bigger than the other dorsal warts => Phigalia pilosaria
* If there´s only substantial bigger warts out, lateral (segm 5) => Apocheima hispidaria.
It doesn´t matter about any colourdifferences - it´s only concerning about the size of the warts.
I have checked the "rule" up on all public inspiring confident material (photos) on the net, and it works!
Including Lepiforum, itself:
Go and see
Therefore: My larva is an Apocheima hispidaria (no big warts, dorsally)
