狼狼蛛的猎物85%由双翅目、半翅目和蜘蛛目组成。在一年中的不同时间，蜘蛛所摄取的食物似乎有所不同;这更可能是由于猎物丰富度的变化，而不是蜘蛛偏好的变化。L. lugubris不是一个活跃的捕食者。它不追逐猎物，而是一动不动地抓住触手可及的东西。它可能很少在野外觅食，它携带猎物一至两个小时。人们试图评估可能的捕食者，这个物种可能是它自己最重要的捕食者。
85 % of the prey ofLycosa lugubris (Walckenaer) consists of Diptera, Hemiptera and Araneae. The food taken appears to differ at different times of year; this is more probably due to changes in abundance of prey than to changes in preference by the spider. L. lugubris is not an active predator. It does not run down its prey but remains motionless and captures what comes within reach. It probably feeds infrequently in the field and it carries its prey for between one and two hours. An attempt was made to assess possible predators, and the species may be its own most important predator.
