-在北半球的阔叶落叶林中，许多木本双子叶植物的叶下表面的叶脉腋处经常出现叶斑病。这些结构经常被螨类用作庇护所和产卵地点。在威斯康星州中部S的拉瓦勒附近进行的6种乔木或木本藤本植物(Quercus velutina、Q.rubra、Acer Saccharum、Prunus virginiana、P serotina和Vitis riparia)的研究表明，捕食性和食草性螨类的分类群与6种乔木或木本藤本植物的主权区有关。对不同叶微生境(叶脉、主脉腋叶、中脉沿脉和叶层)中的叶螨的频率和丰度的比较表明，叶面结构特征，特别是叶脉结构特征对叶螨有强烈的反应。此外，在五个配对物种的比较中，有四个具有家蝇的物种的叶片上有更频繁的蠕虫证据或更多的蠕虫。潜在有益螨类的丰富，主要是Leucohipeus和Typhlodromus nr.POMI(植蜂科)在有斑点的树种的叶片上显着增加，对草食性螨类的总体益害比也较大。叶蝉是潜在植物互惠者的重要庇护所，它改变了温带阔叶林冠层中叶蝉的分布和丰度。
-Leaf domatia occur frequently in vein axils on the leaf undersurface of many woody Dicotyledonae in the broadleaf deciduous forests of the northern hemisphere. These structures are often used by mites for shelter and as sites for egg laying. Taxa of predatory and fungivorous mites and sometimes of herbivorous mites were associated with the domatia of six species of trees or woody vines (Quercus velutina, Q. rubra, Acer saccharum, Prunus virginiana, P serotina and Vitis riparia) examined near LaValle in S-central Wisconsin. Comparisons of mite frequency and abundance in different leaf microhabitats (in domatia, in major vein axils without domatia, along the midrib, and on the leaf lamina) showed that mites respond strongly to leaf architectural features, especially domatia. Further, mite evidence was more frequent or mites more abundant on leaves of species with domatia in four of five paired-species comparisons. The abundance of potentially beneficial mites, primarily Metapronematus leucohippeus (Tydeidae) and Typhlodromus nr. pomi (Phytoseiidae) was significantly greater and the overall ratio of beneficial to herbivorous mites was greater on leaves of species with domatia. Leaf domatia are important shelters for potential plant mutualists and alter the distribution and abundance of foliar mites in the canopy of temperate broadleaf
