Solpugid or sun Spider
“Anything so ugly MUST be poisonous,” seems to be the principal basis for its unhappy reputation.
It is often found inside buildings where it has gone in search of insect prey, and Mexican families living in adobe houses with dirt floors are reported to be terrorized by it. In Mexico and in many parts of the Southwest it is known as niña de la tierra or child-of-the-earth.
The range of the solpugid or sun spider is by no means limited to the desert, but its reputation as a poisonous creature seems to be much worse in the Southwest than elsewhere.
The solpugid not only is perfectly harmless to man but does not rely on poison in capturing its prey, as it has no venom glands whatever.

Whereas the solpugid is called child-of-the-earth in the southern portions of the Southwest, in the northern part of this territory another creature, the Jerusalem cricket, sand cricket, or chacho is reported as imbued with the same dangerous qualities evidently credited to any creature to which this name has been applied.
