Q: I donât know if this new visitor is a positive or negative for the vegetable garden.
A:Â Your visitor is the Mexican tiger moth (Notarctia proxima). I couldnât say if it is positive or negative for your garden without more information about where you found it and what, if anything, it could have been eating.
The tiger moths can have a diverse diet and have been known to be problematic on certain plants. This species hasnât been studied as much as its more famous relatives the fall webworm, the banded woollybear caterpillar, and the invasive gypsy moth so there isnât as much information about what plants it might like.
