Studies on several insect species exhibiting wing polymorphism (having both winged and wingless morphs) have shown that the reproductive output of wingless adults is higher than their winged counterparts that migrate out of deteriorating habitats. These results have been interpreted as supporting the idea that flight comes at a cost to reproduction. However, this has not been examined carefully in species where all adults are winged and require flight for the location of food, mates and oviposition sites. Furthermore, it has been hypothesized that migrant species have evolved traits to reduce the cost of maintaining flight apparatus on subsequent reproductive output. In my research group we have been using the true armyworm,

对几种表现出翅膀多态性（有翅和无翅变种）的昆虫物种的研究表明，无翅成虫的生殖产量高于从恶化的生境中迁移出来的有翅成虫。 这些结果被解释为支持这样一种观点，即飞行是以繁殖为代价的。然而，这还没有仔细研究的物种，所有的成年人都有翅膀，需要飞行的食物，交配和产卵地点的位置。此外，有人假设，迁徙物种已经进化出的性状，以减少成本，维持飞行器在随后的生殖输出。在我的研究小组中，我们一直在使用真正的粘虫，
