The blue color of O. sp. “Quezon blue” is most evident in freshly molted adults. The species is fast, easily agitated, and defensive. Venom may be medically significant. For these reasons, although it is no trouble to keep, we recommend O. sp. “Quezon blue” for experienced keepers. Females mature at 3-4″, but with subsequent molts have been reported to grow larger.

In the wild, O. sp. “Quezon blue” may be found in rock crevices. In captivity, spiderlings dig a maze of tunnels in loose substrate. Adults also tend to dig. All instars are good eaters and hardy in captivity.
