Hello all! I have been caring for an unidentified queen species since last season in a standard test-tube setup. She was caught in August around the deserts of Joshua Tree, CA. Although she initially laid a brood of eggs, all died during this last winter's hibernation period. Her abdomen has receded during this time as no eggs are currently being produced. However, there is this odd protrusion at the back of her abdomen, wondering if anyone has any idea on what it may be?
