This could be partially due to the massive rains recieved earlier.
Welcome Swallows buzz the nearby dam in flocks approaching fifty in mumber, showing that lavae of all sorts are there for the taking.
Our resident spider species have been taking advantage of this fact also, catching masses of small annoying insects before they gain entry to our home.
There has even been a little time for them to do one of the most dangerous dances of all for a spider - the act of mating.
These two are engaged in that dance.
"Palps" of the male spider, the smaller of the two in the foreground, place sperm into openings in the female while, at least with this species, they face to face as though locked in some mortal combat.
The female spider often eats the male after mating, and sometimes during the act, dependant on the species and how quick the male can make a run for it afterwards.
A danerous dance indeed.
