What is the primary factor limiting the distribution of vinegaroons in the United States?

Answer

Availability of suitable deep soil for burrowing

These arachnids are semi-fossorial creatures that rely on the environment to regulate their body temperature and moisture levels. Because they spend the vast majority of their lives underground, the ability to excavate or find stable, deep, non-compacted soil is the critical requirement for their survival. This geological preference acts as a stronger predictor of where they will be found than broad climate zone classifications.
