在西班牙中部的自然栖息地的生物气候梯度沿着在1年的不同季节的腐肉诱饵陷阱的组成和空间分布的食肉双翅目组合进行了研究。丽蝇科和蝇科是双翅目昆虫中数量最多的科，分别占双翅目昆虫总数的41.9%和35.1%。其他科的种类较多的有花蝇科（8.4%）、麻蝇科（6.9%）和蝇科（5.1%）。不同生物气候水平的蝇类组合组成不同，中地中海生境的优势种为白头蝇（Wiedemann）（双翅目：丽蝇科），超地中海生境的优势种为透明蝇（Harris）（双翅目：蝇科），而高山地中海生境的优势种为黑腹拟蝇（Meigen）（双翅目：粉蝇科）。不同季节的组合组成也存在差异。在秋、冬、春三个生物气候水平上，喜温性物种如丽蝇和一些花蝇在秋季、冬季和春季均有较好的代表性。相比之下，嗜热物种，如Ch. albiceps和丝光绿蝇（Meigen）（双翅目：丽蝇科）和大多数家蝇和麻蝇科物种在夏季和地中海中部栖息地位于低海拔地区更丰富。了解某些物种对某些生境的偏好可能具有生态和法医学价值，并可能为进一步研究奠定起点。
The composition and spatial distribution of sarcosaprophagous Diptera assemblages were studied using carrion‐baited traps along a bioclimatic gradient of natural habitats in central Spain throughout the different seasons during 1 year. Calliphoridae and Muscidae were the most abundant families, accounting for, respectively, 41.9% and 35.1% of all Diptera specimens collected. Other abundant families were Heleomyzidae (8.4%), Sarcophagidae (6.9%) and Piophilidae (5.1%). Fly assemblage compositions differed among bioclimatic levels, with Chrysomya albiceps (Wiedemann) (Diptera: Calliphoridae) being the dominant species in mesomediterranean habitats, Muscina levida (Harris) (Diptera: Muscidae) the dominant species in supramediterranean habitats, and Prochyliza nigrimana (Meigen) (Diptera: Piophilidae) the dominant species in oromediterranean habitats. Differences in assemblage composition were also found among seasons. Thermophobic species such as Calliphora vicina Robineau‐Desvoidy (Diptera: Calliphoridae) and some species of Heleomyzidae were well represented during autumn, winter and spring in the three bioclimatic levels sampled. By contrast, thermophilic species such as Ch. albiceps and Lucilia sericata (Meigen) (Diptera: Calliphoridae) and most Muscidae and Sarcophagidae species were more abundant during summer and in mesomediterranean habitats located at lower elevations. Knowledge of the preferences of some species for certain habitats may be of ecological and forensic value and may establish a starting point for further research.
