[Microhabitat selection by ant-lion larvae Myrmeleon brasiliensis (Návas) (Neuroptera: Myrmeleontidae), in a Forest Reserve, Aquidauana, State of Mato Grosso do Sul].
The relative abundance, density, distribution pattern and relation among pit diameter and larvae body size of Myrmeleon brasiliensis Návas were evaluated in two microhabitats: sheltered and exposed. The total of 282 pits were found in sheltered microhabitat and only 50 in the exposed. The density of M. brasiliensis was between one and 43 individuals per m(2). The distribution pattern of larvae tended from pooled to regular distribution as the density increased. In both microhabitats the larvae body size was positively correlated with pit diameter.
