Facts About

Texas palafox is native to Texas, Florida, Louisiana and Mexico. It is not on record as having been collected anywhere else in North America except for Massachusetts, so it's probably safe to say it is highly ephemeral in our region.

Habitat

Anthropogenic (man-made or disturbed habitats), shores of rivers or lakes
