	Joe Kunkel's discussion of elimination in butterflies omitted two

1) Meconium. This is a liquid, sometimes reddish in color, that is excreted
after eclosion. It has been implicated in some of the cases of 'bloody
rain' in past times. According to Wigglesworth, it consists of urine.

2) 'Pumping'. Sometimes both butterflies and moths will stand by the edge
of a puddle of water, and ingest large amounts of water while simultaneously
excreting drops of a clear fluid. This behavior can last for a long time,
and is known as 'pumping'.
