About
this photo: In his back yard in Grape Creek,
Texas (31 N, -100 W), Mr. Alley discovered this
tagged monarch butterfly. He took this picture so
carefully that you can even read the number on the
butterfly's tag! The monarchs arrived on October
8th and formed a roost. On October 15th, exactly
one week later, the butterflies departed. You can
see a picture of the roost and read his field notes.

Somebody,
somewhere tagged this butterfly sometime
before October 11th, the day Mr. Alley took the
picture. All butterflies must fly through Texas
on their way to Mexico, so it's fun to imagine where
this monarch was tagged.
