I am asking about the Larva - Is it Schreckensteinia festaliella - or is there some dought?
There is no doubt, the larva is Schreckensteinia festaliella.
Is it always "ein Bestimmung" when you see it in the headline?
If the name is put without a question mark it should be the determination. Of course, sometimes there can be a miss determination - we're all human - but normally someone will correct it.
Or is there an mystical, ancient message in the clause:
"Schreckensteinia festaliella - Raupe, Raupe im Habitat, Habitat ==> " ???
This just meant a hint to the administrators that your pictures should be inserted into our BH. This of course can take a little time as all are working voluntarily.
