This fine addition to our list occurred in each case in a stagnant 
pond. The insect has probably evaded earlier collectors by its peculiar 
habit of immediately leaving the surface and descending to the mud at 
the bottom of the pond and burying itself there. To capture it, the 
collector must watch it enter the mud.
