1. Crab spiders (Thomisidae) indirectly affect insect flower‐visitor and flowering plant interactions by consuming and altering the behaviour of insects. 2. Although one expects insect flower‐visitors to avoid crab spiders actively, some crab spider species are known to attract flower‐visitors. Crab spiders may use UV signalling to lure potential prey to the flowers they occupy. 3. In the present study, a field experiment was conducted to examine the effects of crab spiders occupying three prairie plant species for the insect flower‐visitor community. Pollinating insects were significantly attracted to inflorescences with crab spiders compared to inflorescences without crab spiders for two plant species, and herbivorous insects were attracted to inflorescences with crab spiders for one of these plant species. The two flowering plant species with increased pollinator visitation showed increased seed weights for plants with crab spiders, indicating crab spider presence indirectly increased pollination. 4. To test the UV signalling hypothesis, inflorescences with crab spiders of one plant species were observed under both a UV‐blocking plastic and a clear plastic control. Contrary to our prediction, flower‐visitors were not more likely to land on inflorescences under the clear plastic; the UV signalling hypothesis was not supported. Other unknown explanations underlie prey attraction to inflorescences with crab spiders.  相似文献

蜘蛛听毛的电镜观察   总被引:9,自引:0,他引:9  
选用新蛛类的9种蜘蛛作为研究的对象,通过听毛的电镜观察探讨听毛在不同类群的差异。研究结果表明:管网蛛科的北京马蹄蛛的毛窝和听毛显然与中纺类,原蛛类和新蛛类中其他科的种类均不相同。拟壁钱科的居室拟壁钱(有筛器蜘蛛)和北国壁钱(无筛器蛛蛛)的毛窝和听毛的结构相差悬殊,很难看出亲缘上的关系,刺瓣似隙蛛和机敏漏斗蛛的毛窝差别大,无法表明它们之间近缘,园蛛科和肖蛸科种类的听毛窝和听毛数目表明两者之间近缘。  相似文献

A new species, Xysticus jiangi n. sp. is described based on the specimens collected in Hunan province, China. X. jiangi is similar to X. chui, but distinguished by smaller spermathecae, distinct copulatory canals, and Y‐shaped median apophysis. In addition, basal apophysis of tegulum is well developed, compared to that of the latter.  相似文献
