SAN ANTONIO – It happens every year: millions of American snout butterflies -- known colloquially as "snout nose butterflies" -- migrate through San Antonio.
And more than a few of the insects will end up splattered on your car's grill or windshield.
Named for its long nose, the snout nose butterfly is often confused for a moth due to it's grayish-brown camouflaged wings.
These butterflies usually make their way across the Interstate 35 corridor toward South Texas between early August and late September.
However, the friendly fliers are not "calendar insects," meaning they don't follow regular migratory patterns.
As a result, we can't make any inferences about a cooler fall or a warmer winter from their behavior.
What we do know is that the bugs are back and the lines at the car wash may be a bit longer than usual.
Here's some reaction the butterflies that have made their way to the South Texas and San Antonio area.

The butterflies are migrating through San Antonio. I’m just driving home not trying to hit any of them but it is impossible! I’m driving with this face the whole way home. pic.twitter.com/lZlfaJOzle— Jorge Escalante (@EscalanteBrew) September 25, 2018
