FW: snout migration - Kingsville to Falfurrias - July 27

[Mike Quinn]

South Texas, northeast Mexico must have received significant rains prior
to Dolly which made landfall on July 23 in South Padre Island, Texas.
All these swarm reports are too soon for the butterflies to have
developed from the hurricane rains. Mike Quinn, Austin

Larry Gilbert cites Roy Kendall (pers. comm.) as reporting that the
American Snout, under optimal conditions, can go from egg to adult in 16
days.

behavior in two butterflies of the semi-arid shrublands of South Texas.

Fyi, I drove through a snout migration Sunday July 27. I noticed them
from Kingsville at highway 77, along 141, and south on highway 281 until
about Falfurrias. They were moving east, flying low to the ground.

Two weeks ago a large concentration (thousands) was moving between
Kingsville and Sarita. Last week I ran into another large concentration
in northern Jim Wells Co. and saw very little else on the wing between
CC and Austin. They seem to be moving in a generally north by northeast
direction........Charlie

Ran into my first movement of snouts in a couple of years on my way to
San Antonio today.

They were between 84 and 85.5 miles NE of Eagle Pass on Hwy 57. Several
thousand moving low to the ground in a westward direction.
