Why is Plesanemma fucata Geometridae?
I assume that it is not a mistake because it seems that it has been considered Geometridae since 1875.
I previously thought that all Geometridae caterpillars/larvae had only 2 pairs of prolegs, but this species has 5. Are there other exceptions to this rule? Is there a known evolutionary reason that these caterpillars don’t have 2 pairs?
There isn’t a lot of information about the species or even the Plesanemma genus online so I was wondering if anyone here knew.
Thank you for reading.
