Isn't this a long time before insects and such though?

  Wikipedia says: "evidence of arthropod boreholes in Prototaxites has been found from the early and late Devonian, suggesting the organism survived the stress of boring for many millions of years.[30] Intriguingly, boreholes appeared in Prototaxites long before plants developed a structurally equivalent woody stem, and it is possible that the borers transferred to plants when these evolved" and for Arthropods: "The evolutionary ancestry of arthropods dates back to the Cambrian period." which is about 100 million years before the Devonian also: "The oldest known arachnid is the trigonotarbid Palaeotarbus jerami, from about 420 million years ago in the Silurian period.[82][Note 3] Attercopus fimbriunguis, from 386 million years ago in the Devonian period, bears the earliest known silk-producing spigots" so there could have been all sorts of weird and wonderful bugs burrowing into Prototaxites I guess
