- Eye arrangement is similar-looking to that of the “brown recluse” and other species of Loxosceles. Color, pattern, and carapace shape are vastly different, though.
- Subdues its prey with a spray of venom-soaked silk and glue. Typically stalks prey to within 10-15mm and then “spits.” The spit actually shrinks afterwards, helping to constrict the prey (Suter & Stratton 2009); once it’s immobile, the spider moves in to bite and inject venom.
- Usually found at night, slowly wandering around, or simply not moving at all.
- In addition to Scytodes thoracica, there are at least eight other described species of “Spitting Spider” that have been collected in the United States; some may be endemic to the southern states, others may be synanthropic and were introduced from Central and South America via commerce.
- Very simple courtship: the male basically just shows up and touches the female with his legs and then climbs over and under her.
- Egg sacs have around 20-35 eggs and are carried beneath the female’s body, held in her chelicerae (jaws) and, at the same time, tethered to her spinnerets by strands of silk.
