Lyside sulphur (Kricogonia lyside) outbreak in southwest Texas

[Mike Quinn]

FYI,

Lyside sulphurs make periodic mass movements across south Texas
which appear to induced by an extensive drought followed by heavy,
widespread rains.

Lepidopterists’ Society here:

All:  ~10 days ago I drove thru Crystal City etc. and the pale yellow
butterflies out numbered anything I have ever seen including Snout break
outs....These butterflies were literally piled along stretches of 83 like
very shallow snow banks...Semi-trucks radiators were clogged with the
things as were mine...I had to stop in every town I came across to try to
clean the smear off my windshield.  These bugs faded out around mid Webb
county ...My radiator still has a few hundred on it though I have tried to
pressure wash them off...Hard to get to.

PS: Crystal City seemed to be the epicenter but they were everywhere from
north of Laredo to Bracketville.
