Description

Named after Barbara Moore, one of the cofounders of the American Tarantula Society, Aphonopelma mooreae comes from the Mexican state of Sonora, south of Yerora (Yécora). Smith reports habitat as “mostly ironwood desert scrub forests with columnar cacti.” [1] Ironwood is endemic to the Sonoran Desert, which spans the US/Mexico border. Its wood sinks in water and its lifespan exceeds 800 years. Although ironwood and columnar cacti are found throughout the Sonoran Desert, northwest Mexico’s Sonoran differs from its Arizonan counterpart, mainly because of rain from the Gulf of California. This rain falls seasonally on the western slope of the Sierra Madre Occident (SMO) (below, left).

The town of Yécora lies in the SMO at 5,700 ft. At this elevation, pine-oak woodland dominates. Ironwood is not found here.

Intolerant of sustained cold, ironwood occurs below 3280 ft. Elevation is one determinant of forest type and in this region, tropical deciduous forest (TDF) grows at 1500-3000 ft, and transitions to foothills thornscrub (FTS) at 1500 ft. According to Smith’s report, these are the ironwood desert scrub forests expected to support A. mooreae.

However, in a more recent paper, based on “iNaturalist and other online sources,” Hendrixson [3] concludes “A. mooreae is a denizen of the pine-oak woodlands of the northern Sierra Madre Occidental.” Pine-oak woodlands differ greatly from ironwood desert scrub forests.

As for which habitat supports A. mooreae, the preponderance of data seems to suggest higher altitude pine-oak rather than lower altitude TDF/FTS. Collectors and breeders of A. mooreae may benefit from this clarification.*

Spiderlings offered on this page were captive-bred in Mexico. They are actively eating 1/8″ crickets and thriving under conditions normally used for early Aphonopelma instars.
