Zeuzera pyrina spends up to three years inside a single tree before it ever sees light again. That is the timeline it works on. Not the season, not the quarter, not anyone else's schedule. You operate on a timeline that most people around you cannot read, and you have stopped trying to explain it to them.

The leopard moth larva does not eat bark or leaves. It bores directly into heartwood, the densest, most structurally significant tissue a tree has. That is where the nutrition is, and that is where the damage is most profound. You work the same way. You go past the surface of a problem, past the obvious entry point, into the structural core where the real thing lives. This makes your work slow, invisible for long stretches, and then suddenly catastrophic to whatever was pretending to be solid.

When Zeuzera pyrina larvae move through a tree's core, they change the tree's architecture permanently. Even trees that survive the infestation grow differently afterward, rerouting around the tunnels left behind. The systems and people you work through carry the shape of your presence long after you have moved on. Your absence does not leave things as they were. It leaves a structural gap where your depth of engagement used to be.
