目前昆虫分类学仍多以形态特征为基础。已知的种类绝大多数都是根据标本和不完全的分布记录确定的,由于生殖隔离在种的确定上是一个必要的条件,生殖器的差异在种的确定中往往成为主要依据。种群内个体变异是普遍存在的,模式概念已逐步被种群概念所代替。因而脱离种的形态特征或以 At present, insect taxonomy is still based on morphological characteristics. Most of the known species are based on specimens and incomplete distribution records. Since genital isolation is a necessary condition for species identification, differences in genitalia are often the main basis for species identification. Individual variation within the population is ubiquitous, and the concept of patterns has been gradually replaced by the concept of population. Thus departing from the morphological characteristics of or species
