Sonoran Vinegaroon
Mastigoproctus tohono
Mastigoproctus • Thelyphonidae
Overview
The southwestern US vinegaroon (split from the giant vinegaroon), often with a reddish tint. Docile and slow to use its acetic-acid spray — harmless to people (only irritating if it reaches the eyes). No venom, no sting. From arid country that wakes up in monsoon season, so give deep substrate kept dry on top and damp below for a humid burrow, plus a water dish. Room temperature is fine.
