Abstract： The population of Myrmeleon (Morter) sagax (Walker) at Bazhai scenic spot in Danxia Mountain of Shaoguan City, Guangdong Province, was investigated in February, 2009. Five aggregation indices, Iwao’s way (regressive relationship with m*-m), and power law of Taylor were used to evaluate the spatial distribution pattern of ant\|lions. The results showed that ant\|lions were spatially evenly in their distribution range. The higher population density, the more evenly distribution was observed. The evenly distribution pattern of ant\|lions population might be caused by habitat condition, their prey behavior and intraspecific competition.
