一些欧洲品种的蟹蛛会选择与它们所栖息的花朵颜色一致的花朵来伏击昆虫传粉者，这一策略被认为是为了躲避它们的目标猎物和捕食者。在这里，我们展示了一种澳大利亚的蟹蛛，tomisus spectabilis，它隐藏在白色的雏菊菊花上，对人眼来说，对于紫外线敏感的昆虫猎物来说，它的颜色是非常明显的——但是，它并没有像人们想象的那样排斥觅食的蜜蜂（Apis mellifera），相反，蜘蛛与花瓣的对比使花朵更具吸引力。这只蜘蛛显然是在利用蜜蜂对彩色花朵的偏好。
Some European species of crab-spider match the colour of the flower on which they lie in wait to ambush insect pollinators, a tactic that is presumed to camouflage them from their intended prey and from predators,. Here we show that the coloration of an Australian species of crab-spider,Thomisus spectabilis, which is cryptic on the white daisyChrysanthemum frutescensto the human eye, is highly conspicuous to ultraviolet-sensitive insect prey — but that, instead of repelling foraging honeybees (Apis mellifera) as might be expected, the contrast of the spider against the petals makes the flowers more attractive. The spider is apparently exploiting the bee's pre-existing preference for flowers with colour patterning.
