>From the description Eugenie Phillips gave me of the cocoons in Costa Rica
(matches the ones here exactly), it very much sounds like the #1 candidate
is the Nymphuline Pyralid genus _Petrophila_. Now we have some idea what to
expect, and I'm going to be asking the limnology folks here if they have
lep larvae in their aquatic samples from that area - if so, we can at least
get some possible idea of the phenology.

Thanks to all who have responded.
