The Mecoptera of Michigan

The Great Lakes Entomologist, 2017
(excerpt) To date, no one has published on the Mecoptera of Michigan. A comprehensive taxonomic paper on the Mecoptera of Illinois, by Donald W. Webb, Illinois Natural History Survey, and Norman D. Penny, University of Kansas, is in preparation and will include keys to and descriptions of the midwestern species of Mecoptera.

Mecoptera is paraphyletic: multiple genes and phylogeny of Mecoptera and Siphonaptera

Zoologica Scripta, 2002
Phylogenetic relationships among members of the Mecoptera and Siphonaptera were inferred from DNA sequence data. Four loci (18S and 28S ribosomal DNA, cytochrome oxidase II and elongation factor‐1α) were sequenced for 69 taxa selected to represent major flea and mecopteran lineages.

On the structure of the cuticle of Mecoptera

Journal of Entomology Series A, General Entomology, 1975
ABSTRACT The chitin architecture of Mecoptera cuticle is of two kinds: helicoidal and helicoidal preferred with the preferred layers being cross‐plied. Comparison of both systems of terminology currently in use to differentiate the subtypes of cuticle indicates that neither provides much information about the arrangement of chitin ...

Ultrastructure of the larval midgut of Bittacus planus (Mecoptera: Bittacidae) and Neopanorpa longiprocessa (Mecoptera: Panorpidae)

Tissue and Cell, 2017
Bittacidae and Panorpidae are the two largest families in Mecoptera. The larvae of Bittacidae are different from those of Panorpidae in external morphology and habits, and have an interesting habit of spraying the body surface with soil through the anus.

New Species of Neopanorpa (Mecoptera) from Vietnam, with a Key to the Species of Mecoptera of Vietnam

Proceedings of the Entomological Society of Washington, 2017
Abstract. Sixteen species of scorpionflies have been reported from Vietnam, consisting of 13 Neopanorpa and three Bittacus species. One of these scorpionflies from the Central Highlands of Vietnam with hood-shaped hypovalves was determined to be a new species and is described herein as Neopanorpa cucullata, n.sp.

Ultramorphology of the proventriculus in Panorpidae and Bittacidae (Mecoptera)

Micron, 2009
The proventriculus is a specialized part of the foregut in the alimentary canal in some insects, varying greatly in its structure across different insect groups. The ultramorphology of the proventriculus in Mecoptera was investigated in eight species of Panorpidae and one of the Bittacidae using light microscopy and scanning electron microscopy.

The phylogenetic system of the Mecoptera

Systematic Entomology, 1987
Abstract. Many families like the Mesochoristidae, Agetopanorpidae and Permopanorpidae, which were believed by earlier writers to be Mecoptera, are members of the stem group of the Antliophora (Diptera Mecoptera+Siphonaptera) or of stem groups of monophyletic groups of even higher rank (e.g.

Additions to the Mecoptera of Mexico

Journal of the Kansas Entomological Society, 2011
Abstract Three new Mexican species of Panorpidae, Panorpa accola, Panorpa michoacana, Panorpa teziutlana, and one bittacid, Eremobittacus sodalium, are described, illustrated and compared to previously named species. Distributional notes are added for some other species from Mexico.

Scorpionfly larvae (Mecoptera)

2002
Larger, terrestrial members of this order of insects hold their abdomens with a distinctly scorpion-like posture and this is where they get their name.
