calla lily leaves have thin black squiggly lines

Question

My calla lilies look like they have leafminers, but the lines are black. What are they?

Answer 1

In my research I have not been able to fine a pest that leaves a trail like the one you describe.

Neem Oil can be used to treat most infestations on plants.
