Here are my feeling, very unscientific. If you believe that alterna survive the brutal Texas southwest because there are oasis-like aquifers slightly underground, and a drought has caused them to take a long earned sabbatical from terrestrial happenings, then I wouldn't discount the ultimate call to survival, for two straight years in a row. I predict that regardless of the actual rainfall from May until June, that they will mate, and mate HARD this year. They have survived for thousands of years, and this small, yet non-insignificant event will do little to deter them.
