利用摄影技术研究了五龄若虫的摄食行为，通常以60秒的间隔在彩色胶片上曝光。在乳草种子的天然饮食中，进食以平均约22小时的周期发生，由2至6小时的非活动间隔隔开。摄食活动约占每个主要摄食周期的75%。在成虫（最终）蜕皮前48小时内没有进行喂食。取食强度和取食行为的特点显着影响的存在或不存在的马利筋种皮。对正常摄食很重要的种皮因子尚未确定，但推测其本质上是趋化性的。在早期的工作中开发的纯化饮食的明显缺陷被证明是没有营养的;相反，它们与这种饮食未能满足该错误的进食要求有关。
Feeding behavior of fifth-instar nymphs was studied utilizing a photographic technique with exposures on color film made, usually, at 60-second intervals. On the natural diet of milkweed seed, feeding occurred in cycles averaging about 22 hours, separated by inactive intervals of 2 to 6 hours. Feeding activities occupied about 75% of each major feeding cycle. No feeding was done during the 48 hours preceding the imaginal (final) ecdysis. Intensity of feeding and characteristics of feeding behavior were markedly influenced by the presence or absence of the milkweed seed coat. The seed coat factors important to normal feeding have not been identified, but are presumed to be chemotactic in nature. The apparent deficiencies of a purified diet developed in earlier work were shown not to be nutritional; instead, they were related to a failure of this diet to meet the feeding requirements of the bug.
