Re: [GSAS-Member] water boatman

Trish,

I am sure you were observing insects that emerged from the water and flew.  
Most aquatic insects do.  I wasn't finding fault, I was talking about water 
boatmen.

Sorry for the slow reply.  I am attending meetings in Southern Cal, where the 
clouds of smoke are now being replaced by the clouds of change.
