Texas Sage eaten by caterpillars? Take a close look at your Texas sage and see if you find small black spiny caterpillars.
They are the larvae of the Silvery Checkerspot Butterfly.
Although they are small they have a huge appetite for sage leaves. They can devour the leaves of your plant in a matter of days. They are easily killed with Thuricide, Dipel dust or Spinosad and your plants will leaf back out in no time.
