BURROWING (***NEW DATA***):
For a long time enthusiasts were puzzled by roses' apparently
unwillingness to burrow in a cage. It was thought that they might be
vagabonds in nature, seldom if ever actually living in a formal burrow.
However, recently Dr. G. B. Edwards (Curator: Arachnida & Myriapoda
Florida State Collection of Arthropods, FDACS, Division of Plant Industry)
on a trip to Santiago Chile, examined Chilean rose tarantulas in large
numbers living in burrows some 45 centimetres (18 inches) deep. Now we
know: Their apparent reluctance to dig a burrow in captivity is apparently
an artifact of being captive, not a "natural" life style.
The general experience in the hobby is that they neither require a burrow
nor use one. When given the chance we've seen them use a coconut shell as
a place to hide, but all of ours have firmly rejected burrows when they
have been offered. This is supported by the experience of many other
keepers. Installing a coconut shell or a plastic aquarium plant that
drapes over to produce a darkened cave-like space might be appreciated,
however. It may decide that's a good place to hide. Otherwise, don't worry
about it.
