Hemiptera - 1 This leaf pack was an experiment to utilize the wetland internal vegetation opposed to leaves from outside of the wetland. The purpose was to compare the differences in colonization of the material between wetland veg and surrounding deciduous tree leaves. Wetland vegetation in these leaf packs consisted of bullrush/scirpus and cattail/typha. Standing water veg consisted of 100% scirpus, while typha was located on the wetland perimeter.
