摘要1根据对数序列，对在塞拉利昂采集的三个狮身人蛛科样本进行了物种多样性估计。两种独立的抽样方法给出的值没有显著差异。2最常见的狮身人面蛛科种类出现在一年中的所有月份，但一些最丰富的物种在3-5月雨季开始时达到高峰。多样性随着数量的增加而下降，多样性最低值出现在蛾最多的时候。3给出了1966年至1969年在塞拉利昂采集的67种狮身人面蛛科的注释名录。
Summary 1 Estimates of species diversity based on the logarithmic series are given for three samples of Sphingidae collected in Sierra Leone. Two independent methods of sampling gave values that did not differ significantly. 2 Most common species of Sphingidae occurred in all months of the year, but some of the most abundant species reached peak numbers with the onset of the rainy season in March to May. Diversity falls as numbers rise and the lowest values of diversity were obtained when the moths were most abundant. 3 An annotated list is given of 67 species of Sphingidae collected in Sierra Leone in 1966 to 1969.
