在婆罗洲和印度-澳大利亚热带其他地方的大量捕光样本中，我们使用了我们自己的定量捕光样本，并补充了其他收集者已公布和未公布的数据，对Sphingid生物多样性进行了比较。没有观察到人为生境干扰对生境内多样性(以Fisher‘s Alpha衡量)的影响，但在不同干扰程度下，群落的区系组成明显不同。海拔高度、采样年份和采样制度(全夜与部分夜间)被确定为影响当地样品组成的附加参数。在不同的干扰条件下，亚科出现的频率不同：从原生生境到重度干扰地，亚科的分布呈梯度递减趋势，而巨舌亚科则呈现相反的趋势。讨论了亚科对干扰和海拔的反应之间的关系以及亚科之间潜在的生活史差异。假设，资本繁殖的Smerinsinae可能更普通，更擅长稳定的主要栖息地，而许多收入繁育的Macroglossinae可能适应在短暂的、受干扰的生境中茁壮成长。此外，我们还表明，从当地样本估计的物种丰富度比婆罗洲已知的全部物种丰富度低约10%。
Sphingid biodiversity was compared in a large number of light-trapping samples on Borneo and elsewhere in the Indo-Australian tropics, using our own quantitative light-trapping samples supplemented by other collectors' published and unpublished data. No effects of anthropogenic habitat disturbance on the within-habitat diversity (measured as Fisher's alpha) were observed, but the faunal composition of assemblages differs significantly under varying degrees of disturbance. Altitude, year of sampling and sampling regime (full night vs. part of the night) were identified as additional parameters that influence the composition of local samples. The frequency of subfamilies in samples varies under different disturbance regimes: Smerinthinae decline along a gradient from primary habitats to heavily disturbed sites, while Macroglossinae show the reverse trend. Connections between the reactions of subfamilies to disturbance and altitude and potential life-history differences between the subfamilies are discussed. Hypothetically, capital breeding Smerinthinae might be commoner and more speciose in stable primary habitats, whereas many income breeding Macroglossinae are probably adapted to thrive in ephemeral, disturbed habitats. Furthermore, we show that estimates from local samples fall short of the total known species richness of Borneo by about 10%.
