Cobaltmarsh Moth Catalog

Cataloging begins one hour after sunset at the third wooden marker east of the ferry path. A shielded reed lamp provides the only light. Recorders count a moth after it lands, noting the wing edge, the number of pale spots, and the plant supporting it. Individuals that circle the lamp without resting are listed separately so repeated passes do not inflate the nightly total.

Blue pigment alone is not enough for confirmation because marsh mist can tint ordinary wings. The Cobaltmarsh Moth Catalog requires a hooked lower marking and a still interval lasting five breaths. Accepted records also include cloud cover and the height of the mineral pool. Together, these details guide reed cutting away from the sheltered stems most often used during the warmest new moon.
