The blow fly, Calliphora vicina (Robineau-Desvoidy, 1830) and the green bottle fly, Lucilia sericata (Meigen, 1826) were collected from the north coast of Egypt. The karyotype of both flies was characterized by cytotaxonomical methods, including chromosome number, shape, relative length, arm ratio, centromeric index and designation. To quantify relative chromosome length, the percent of total haploid autosomal complement length (%TACL) for each autosome was calculated. The deploid number of chromosomes, of both flies, is 2n=12 where females have XX and males have XY sex determination mechanism. C. vicina have four metacentric autosomal pairs, with variable arm ratios, and one submetacentric pair. Both X & Y chromosomes are metacentric whereas X chromosome is the longest chromosome in the designation. The karyotype of L. sericata is characterized by the first autosome which is somewhat longer than all other chromosomes (%TACL=27.02). The autosomes of L. sericata are four metacentric pairs and one submetacentric pair. X & Y chromosomes are metacentric & submetacentric, respectively.
红头丽蝇（Calliphora vicina，（罗宾诺 - 德沃伊迪，1830年））和丝光绿蝇（Lucilia sericata，（梅根，1826年））采自埃及北海岸。采用细胞分类学方法对两种苍蝇的核型进行了表征，包括染色体数目、形状、相对长度、臂比、着丝粒指数和命名。为了量化相对染色体长度，计算了每个常染色体单倍体常染色体组全长百分比（%TACL）。两种苍蝇的二倍体染色体数均为2n = 12，其中雌性具有XX，雄性具有XY性别决定机制。红头丽蝇有四对中着丝粒常染色体，臂比可变，还有一对亚中着丝粒染色体。X和Y染色体均为中着丝粒，而X染色体是命名中最长的染色体。丝光绿蝇的核型特征是第一条常染色体比所有其他染色体稍长（%TACL = 27.02）。丝光绿蝇的常染色体有四对中着丝粒染色体和一对亚中着丝粒染色体。X和Y染色体分别为中着丝粒和亚中着丝粒。
