Advertisement I just found my very first tarantula, a female Pterinochilus murinus in a death curl. I got her as a juvie in February of '03. I'm not sure what the cause of death could be besides old age. She has been refusing food the past couple of months. I thought she was gearing up for another molt, but I guess not. I've had her longer than I've even known my husband. I noticed some weight loss, and she has been listless for the past couple of weeks.
