In some groups of insects, the mesonotum is hypertrophied, such as in Diptera, Hymenoptera, and Lepidoptera), in which the anterior portion of the mesonotum (called the mesoscutum, or simply "scutum") forms most of the dorsal surface of the thorax.
•
In Diptera and Hymenoptera the mesothoracic scutellum is also distinct, but much smaller than the mesoscutum.
In apocritan Hymenoptera (wasps, bees and ants), the metasoma consists of the second abdominal segment (which typically forms a petiole) and those segments posterior to it, and is often called the gaster rather than referring to it as the "abdomen"; in these insects, the first abdominal segment is called the propodeum and is fused to the thorax.
In the suborder Apocrita of the Hymenoptera, the first abdominal segment is fused to the metathorax, and is then called the propodeum.
A smaller but historically important (especially for bees of the eastern USA) and rapidly increasing portion of the collection is dedicated to Hymenoptera.
For example, in Diptera, Hymenoptera, and Lepidoptera, the mesonotum is the most hypertrophied sclerite, and is commonly called the scutum.
In higher insect orders from Orthoptera to Hymenoptera, each of the primary lobes is divided into two secondary lobes or phallomeres, termed parameres and mesomeres (NB: this use of the term "mesomere" is not to be confused with the same term in segmentation embryology.
Pinicola Vieillot, 1808 (Aves, Fringillidae) makes the name Pinicola Brébisson, 1818 a junior homonym and therefore unavailable for a genus of Xyelidae (Insecta, Hymenoptera).

A few species, notably insects of the orders Hymenoptera (ants, bees and wasps) and Isoptera (termites) show an extreme form of sociality, involving highly organized societies, with individual organisms specialized for distinct roles.
In Puerto Rico 9 insect species in the orders Homoptera, Hymenoptera, Lepidoptera, and Thysanoptera have been reported as feeding on various parts of S.
Queller and Strassmann (1998) distinguished between "life insurers", which include most Hymenoptera, where cooperation reduces the risk of total reproductive failure, and "fortress defenders", where cooperation enhances the defense of a commonly held, valuable resource.
Thekke Kuruppathe Narendran (February 24, 1944 – December 31, 2013) was an Indian entomologist specializing in the systematics of parasitic wasps in the superfamily Chalcidoidea (Hymenoptera).
In the Apocritan Hymenoptera, the first abdominal segment is fused to the metathorax, where it forms a structure known as the propodeum.
All Tachycineta swallows are known to be exclusive insectivores; only identified prey include Diptera, Coleoptera, Hymenoptera, Hemiptera, and Aranae.
The Vespoidea are a superfamily of order Hymenoptera of class Insecta, although older taxonomic schemes may vary in this categorization, particularly in their recognition of a now-obsolete superfamily Scolioidea.
