As indicated by its name ( meaning “happy”), this spider is not aggressive and usually bites only when pressed against human skin, such as when putting on an article of clothing. Like all sicariid spiders, the venom of the Chilean recluse contains the dermonecrotic agent Sphingomyelinase D, which is otherwise found only in a few pathogenic bacteria.
