First decision

Investigate molting and exuviae

You found an exuvia, white ring, incomplete molt or changed post-molt animal.

Use the whole card. The action stays attached to what must be observed and recorded, plus the nearest inference or action the current guidance cannot support.

Observe first

Distinguish an empty intact exuvia from an animal, then record posture, movement, body region, water and affected denominator.

First action

Leave an ordinary exuvia unless it creates a specific problem, and investigate repeated abnormal events through measured system history.

Record next

Record event time, photographs, animal outcome, recent GH and water changes, diet changes, temperature and colony-wide frequency.

Stop boundary

A white ring is not a diagnosis or certain cause of death, and one molt does not prove a mineral deficiency or treatment need.
