Effects of age on the courtship, copulation, and fecundity of Pardosa pseudoannulata (Araneae: Lycosidae).

abstract：:The tip of the tail in female Cerastes vipera, a small viperid snake, is black and conspicuous, whereas that of the male is not. We tested the hypothesis, albeit indirectly, that this sexual dimorphic chromatisation is related to caudal luring, a feeding mimicry hunting strategy. C. vipera can hunt nocturnally-active ...
