Orphnaecus sp. “Quezon blue” (Quezon blue earth tiger) from Quezon Province, Luzon, Philippines, captive bred. A feisty, medium-size, Old World tarantula with understated blue, most evident post molt. Recommended for experienced keepers.
The Republic of the Philippines has over 7,500 islands. The larger of these host one or more Orphnaecus species. Both Orphnaecus sp. “Quezon blue” and Orphnaecus pillitus, for example, inhabit Luzon, the northern-most and most populous island. Similarly, Orphnaecus philippinus and Orphnaecus sp. “Negros” inhabit the island of Negros.
Orphnaecus sp. “Quezon blue,” the subject of this entry, is from Quezon Province, Luzon. In overall appearance and behavior it is similar to Orphnaecus sp. “blue Panay,“ from Panay Island, directly south of Luzon.
Climate in the Philippines varies according to location west to east, with distinct dry and wet seasons on the western side, and mixed patterns of increased rainfall on the eastern side. Rain in the Philippines depends mainly on ocean currents such as El Niño, elevation, and season. Except for O. sp. “Quezon blue,” the Orphnaecus species mentioned above come from western regions, with distinct dry seasons. Quezon Province on the other hand, receives rain throughout the year, as shown on this Philippines climate map.
Orphnaecus sp. “Quezon blue” characteristics
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.
