The mitochondrial genomes of Panorpidae: sequence, structure and phylogenetic analysis

open access: yes, 2020
Abstract Background: Mitochondrial genomes play a significant role in reconstructing phylogenetic relationships and revealing molecular evolution in insects. However, only two species of Panorpidae have been documented for mitochondrial genomes in Mecoptera to date.Results: We obtained complete mitochondrial genomes of 17 species of Panorpidae.

Death Feigning in Larvae of Scorpionflies (Mecoptera: Panorpidae): Frequency and Postural Changes Based on Larval Instars [PDF]

open access: yes
Death feigning is thought to have evolved primarily as a predator avoidance behavior, and has been reported in 10 of the 31 orders of insects. However, there have been no reports of death-feigning behavior in Mecoptera species.
