The larvae of tent caterpillars display a diversity of lifestyles, ranging from solitary individuals to simple aggregations to highly integrated societies. There are six Malacosoma species in North American as well as five European species. Social complexity in this group is defined in terms of interaction and communication between group members, and is thought to be correlated with patterns of host plant utilization and foraging. The diversity of social forms in this genus provides a model system for the elucidation of ecological correlates to the evolution of sociality, as well as of the ways in which sociality may influence host plant use. Phylogenetic relationships among species of the social tent caterpillar genus Malacosoma (Lepidoptera: Lasiocampidae) will be assessed through application of cladisitic methods to gene sequence data to investigate patterns of social-behavioral evolution in this group. Some tent caterpillars are economic pests and better knowledge of the group-living characteristics of this group is of important economic interest to homeowners and farmers.

帐篷毛虫的幼虫表现出多样化的生活方式，从孤独的个体到简单的群体，再到高度融合的社会。北美有6种软体软体动物，欧洲也有5种。这个群体的社会复杂性是由群体成员之间的相互作用和交流来定义的，并被认为与寄主植物的利用和觅食模式有关。该属社会形态的多样性为阐明社会性进化的生态相关性以及社会性可能影响寄主植物利用的方式提供了一个模式系统。通过对基因序列数据的碎裂分析，将评估软体毛虫属(鳞翅目：软毛虫科)物种之间的系统发育关系，以研究这一类群的社会行为进化模式。一些帐篷毛虫是经济害虫，更好地了解这一群体的群居特征对房主和农民具有重要的经济利益。
