植物的叶子被各种建造庇护所的昆虫所利用。一些昆虫由于难以将树叶改造成庇护所而限制了它们在寄主植物上的使用，而另一些昆虫可能通过不同的建造方法来应对。在这里，我们证明了卷叶象Phymatapoderus pavens(鞘翅目，Attelabidae)根据叶的形状构造了两种类型的叶对棉铃虫Boehmeria Silvestrii的ⅼ。雌象在叶片较小且裂片较弱时利用整片叶片卷叶，而在叶片较大且裂片较深时仅使用其中一个侧裂片。这两种类型都是在一个种群中发现的，每一种类型都是后代生长的场所。在构建每个卷叶时，象甲对叶脉的叮咬不同，这表明卷叶的类型在卷叶之前就确定了。与另一种卷叶象甲Apoderus preecellens(鞘翅目，Atelabidae)相比，Popderus preecellens(鞘翅目，Atelabidae)在灯盏花科(Isodon umbrosusvar.hakusanensis)类似浅裂的叶片上形成卷叶，由于这些象甲能够在叶片的侧面裂片上形成卷叶，因此它利用了更广泛的叶形。卷叶行为、叶脉模式以及害虫和叶片的相对大小的差异是影响结果的因素。
Plant leaves are utilized by various shelter-building insects. Some insects are constrained in their host plant use by the difficulty in modifying leaves into shelters, while others may cope through different construction methods. Here, we show that the leaf-rolling weevilPhymatapoderus pavens(Coleoptera, Attelabidae) constructs two types of leaf rolⅼ onBoehmeria silvestrii(Urticaceae) according to the shape of the leaf. Female weevils make leaf rolls using the whole leaf when the leaf is small and weakly lobed, whereas they use only one of the lateral lobes when the leaf is large and deeply lobed. Both types were found within a population and each functioned as a site for the growth of offspring. Weevils bite the leaf veins differently when constructing each of these leaf rolls, suggesting that the leaf roll type is determined before the leaf is rolled. Compared with another leaf-rolling weevil species,Apoderus praecellens(Coleoptera, Attelabidae), which makes leaf rolls on similarly lobed leaves ofIsodon umbrosusvar.hakusanensis(Lamiaceae),P. pavensutilizes a wider range of leaf shapes because these weevils are able to construct leaf rolls on the lateral lobes of the leaves. Differences in leaf-rolling behaviour, leaf venation pattern, and the relative size of weevils and leaves are factors affecting the results.
