Wood Borer Moth Frass
Larvae of wood boring moths (Sesiidae or Cossidae) leave distinctive piles of frass under the bark of host trees. The frass pellets are cylindrical in shape. I believe this frass was left by clearwing moth larvae (Sesiidae) because the pellets were only a couple mm long.
**In this photo, you can see small bits of silk and tiny wood chips, which prove that this is the frass of a wood boring moth rather than a beetle.
