Notes

Carpenterworm moths are among the largest of the "micro-moths." The larvae, which take approximately two years to mature, bore tunnels in the sapwood and heartwood of trees, which can impact the commercial quality of lumber.

Conservation Status

• Global status: G4 (apparently secure)
• National status: N4 (apparently secure)
• Indiana status: NR (not ranked)

Floral Associates

Little Carpenterworm Moth caterpillars bore into the wood of their host species, creating tunnels. They will spend about two years in the sap and heartwood of the tree before emerging. Adults do not feed.
