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

In 1888 one “Dr. Ludwig” collected a blue spider in Paraguaná, Republic of Venezuela. E. Strand described the preserved specimen in 1907; 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). Desert may not be the first thought given a Venezuelan endemic, but Paraguaná’s biogeography contrasts with continental Venezuela, home to Psalmopoeus irminia and Theraphosa blondi. Indeed, knowledge of Paraguaná’s biogeography and climate has helped surmount C. cyaneopubescens breeding difficulty.

Raising C. cyaneopubescens is easy. All instars are hardy, particularly so beyond the first few. Desert conditions need not (best not) be mimicked—in the wild this spider spends most of its time in a cooler and more humid burrow. Captive specimens seem to prefer hides to digging, and webbing is extensive. Adult coloration appears at 3” or so. Temperament is mid-range so best to avoid mishaps by keeping hands away.
