1. 一群居采叶蝇攻击Rumex sp.。一窝卵的幼虫都栖息在同一个矿区。2. 卵批大小因寄主植物而异，并与叶片大小相关。3. 在田间测定了卵卵数随卵数变化的幼虫存活率。将该指标纳入离合器尺寸优化模型，得到了离合器尺寸预测结果。4. 预测的最佳离合器尺寸为3，是该领域最常见的。
1. Pegomya nigritarsis Zetterstedt in a gregarious leaf-mining fly attacking Rumex sp. The larvae from one clutch of eggs all inhabit the same mine. 2. Egg-batch size varies between host plants and is correlated with leaf size. 3. On Rumex obtusifolius L. larval survival as a function of clutch size was measured in the field. This measure was incorporated in an optimal clutch size model and a clutch size prediction obtained. 4. The predicted optimal clutch size, three, is the most frequently found in the field.
