Crab spider on Texas pricklypoppy (Argemone aurantiaca). The first photo was shot under 365 nm UV light, and the second photo was taken with regular white light flash. The pricklypoppy flower is pure white under visible light and is dark red under UV, not the brilliant white that is typical of most white objects under UV light. The crab spider shines so brightly with fluorescence that it reflects off the flower.
