斯氏柳条线虫将它们的卵分布在不同质量的可用产卵地点(含水的猪笼草叶)上。我用实验检测了对场地质量的三个组成部分的反应：同种幼虫密度、猪笼草的幼虫密度、克氏Metriocnemus Knabi和猪笼子的大小。对幼虫处理的反应是复杂的，显然是次优的。虽然同种幼虫较少和吸虫幼虫较多的叶片中蚊子幼虫的表现较好，但雌性蚊虫在这样的水罐中产卵并不多。相反，在含有蚊虫或蚊子幼虫的实验水罐中产下的卵更多，而在既不含蚊子幼虫又含有蚊子幼虫的水罐中产卵较少。在较大的水罐中产下的鸡蛋更多，这往往会积累更多的资源，而不太容易干涸。因此，虽然产卵决策是次优的，但它们比随机决策要好。
Wyeomyia smithii mosquitoes distribute their eggs across available oviposition sites (water-holding pitcher plant leaves) of varying quality. I experimentally examined responses to three components of site quality: conspecific larval density, larval density of the pitcher plant midge, Metriocnemus knabi, and pitcher size. Responses to larval treatments were complex and apparently suboptimal. Although mosquito larval performance is better in leaves with fewer conspecific and more midge larvae, females did not lay more eggs in such pitchers. Instead, more eggs were laid in experimental pitchers containing either midge or mosquito larvae, but fewer eggs in pitchers with neither or both. More eggs were laid in larger pitchers, which tend to accumulate more resources and dry out less often. Therefore, although the oviposition decisions made were suboptimal, they were better than random.
