Abstract

The distribution of entangled insects (=actual prey) in symmetrical and asymmetrical orbwebs of four tropical araneid spiders was studied. Both web types show a inhomogeneous insect distribution between individual web sections. Possible explanations are discussed but do not completely explain the inhomogeneous insect distribution.

摘要

研究了四种热带园蛛科蜘蛛的对称和不对称圆网中被缠住的昆虫（即实际猎物）的分布情况。两种网型在各个网区之间的昆虫分布都不均匀。文中讨论了可能的解释，但这些解释并不能完全说明昆虫分布不均匀的现象。
