TL;DR: The phylogeny of all major insect lineages reveals how and when insects diversified and provides a comprehensive reliable scaffold for future comparative analyses of evolutionary innovations among insects.
Abstract: Insects are the most speciose group of animals, but the phylogenetic relationships of many major lineages remain unresolved. We inferred the phylogeny of insects from 1478 protein-coding genes. Phylogenomic analyses of nucleotide and amino acid sequences, with site-specific nucleotide or domain-specific amino acid substitution models, produced statistically robust and congruent results resolving previously controversial phylogenetic relations hips. We dated the origin of insects to the Early Ordovician [~479 million years ago (Ma)], of insect flight to the Early Devonian (~406 Ma), of major extant lineages to the Mississippian (~345 Ma), and the major diversification of holometabolous insects to the Early Cretaceous. Our phylogenomic study provides a comprehensive reliable scaffold for future comparative analyses of evolutionary innovations among insects.

TL;DR: Different techniques and analytical methods used in current projects on insect morphology and phylogeny and their optimized combined application and the role of insect morphology in the “age of phylogenomics” is discussed.
Abstract: A brief account of the history of insect morphology is given. Different techniques and analytical methods used in current projects on insect morphology and phylogeny and their optimized combined application are described. These include fixation, dissection, maceration, histology (microtome sectioning), scanning electron microscopy (SEM), transmission electron microscopy (TEM), serial block-face scanning electron microscopy (SBFSEM), focused ion beam scanning electron microscopy (FIB/SEM), confocal laser scanning microscopy (CLSM), bleaching, micro-computed tomography (μCT), computer-based three-dimensional reconstruction, focus stacking of digital images, geometric morphometrics and the storage of morphological metadata. The role of insect morphology in the “age of phylogenomics” is discussed.

TL;DR: A phylogenetic analysis of protein-coding genes from all major insect orders and close relatives was performed by Misof et al. as discussed by the authors, who used this resolved phylogenetic tree together with fossil analysis to date the origin of insects to ~479 million years ago and to resolve longcontroversial subjects in insect phylogeny.
Abstract: Toward an insect evolution resolution Insects are the most diverse group of animals, with the largest number of species. However, many of the evolutionary relationships between insect species have been controversial and difficult to resolve. Misof et al. performed a phylogenomic analysis of protein-coding genes from all major insect orders and close relatives, resolving the placement of taxa. The authors used this resolved phylogenetic tree together with fossil analysis to date the origin of insects to ~479 million years ago and to resolve long-controversial subjects in insect phylogeny.

TL;DR: This is the first report of the strepsipteran species Eoxenos laboulbenei De Peyerimhoff, 1919 and Mengenilla sp.
Abstract: This is the first report of the strepsipteran species Eoxenos laboulbenei De Peyerimhoff, 1919 and Mengenilla sp. Hofeneder, 1910 on the Balearic Islands. Several males of E. laboulbenei were found in samples obtained using a UV light suction trap on a cattle farm in Majorca in October 2012. A number of empty male and female puparia of Mengenilla sp. were found in Ibiza in April 2003.
