由于目前分布不均匀，种类贫乏的蝎蛉科的历史非常有趣。蝎蛉属的唯一化石是在波罗的海琥珀中发现的两个物种，分别于1856年和1954年被发现。第三个物种，Panorpodes weitschati sp. nov.，在此描述。提供了新的诊断和描述以及所有Panorpodes化石物种的新图纸，包括第一幅P.hageni翅膀的插图。化石蝎蛉展示了三种截然相反的翅膀标记模式，从短尾蝎蛉高度透明的翅膀，到带有深色条纹和斑点的魏氏蝎蛉的透明翅膀，到黑翅，只有窄的透明带的P.hageni。化石标本的特点是翅脉序变异很大，即使在一个单一的标本，类似于生活的物种。
The history of the species-poor family Panorpodidae is very interesting due to its uneven present distribution. The only fossils of the genus Panorpodes are two species known from Baltic amber, described in 1856 and 1954. A third species, Panorpodes weitschati sp. nov., is herein described. New diagnoses and descriptions as well as new drawings of all fossil species of Panorpodes are provided, including the first illustration of the wing of P. hageni. Fossil Panorpodes display three diametrically opposed patterns of wings markings, from the highly transparent wings of P. brevicauda, through transparent wings with dark bands and spots of P. weitschati sp. nov., to the dark wings with only narrow transparent bands of P. hageni. The fossil specimens are characterized by a great variability in wing venation, even in a single specimen, similar to that of living species.
