Chromatopelma cyaneopubescens • 1 1/2″ ♀

Female, juvenile Chromatopelma cyaneopubescens (green bottle blue tarantula), captive bred, endemic to the Paraguaná Peninsula, Venezuela. Affectionately referred to as “GBB,” C. cyaneopubescens is both colorful and hardy.


In 1888 “Dr. Ludwig” collected a blue spider in Paraguaná, Venezuela (Republic of Venezuela). Embrik Strand described the preserved specimen in 1907 and after a genus revision it became known as Chromatopelma cyaneopubescens.

Paraguaná is a peninsula in northern Venezuela. But for a tiny isthmus it is an island in the Caribbean, with some texts classifying it as the westernmost of the Lesser Antilles. Paraguaná has a dry climate associated with coastal dunes and desert flora (Paraguaná xeric scrub [shrub]) and fauna.

Desert may not be one’s first thought given a Venezuelan endemic, but Paraguaná’s biogeography contrasts with continental Venezuela, home to Avicularia minatrix, Psalmopoeus irminia and Theraphosa blondi. Indeed, knowledge of Paraguaná’s biogeography and climate has helped surmount C. cyaneopubescens‘ breeding difficulty.

Fortunately, raising C. cyaneopubescens is easy. All instars are hardy, particularly so beyond the first few. Desert conditions need not (best not) be mimicked—in nature this spider spends most of its time in a burrow. Captive specimens seem to prefer hides to digging; webbing is extensive.

Adult coloration appears at 3” or so. Temperament is mid-range so best to avoid mishaps by keeping hands away.
