Lepidopteran research Haug et al. (2026) report evidence from the study of caterpillars preserved in different types of amber indicative of increase of maximum length of protruding structures of caterpillars (such as hairs or spines) through time, and of increase of abundance of caterpillars relative to lacewing larvae through time. Takahashi, Saito & Aiba (2026) describe a forewing of Aporia potanini from the Pliocene-Pleistocene strata of the Teragi Group (Japan), representing the oldest fossil record of an extant butterfly species reported to date.

Dipteran research Peixoto et al. (2026) interpret trace fossils from the Lower Cretaceous Botucatu Formation (Brazil) assigned to the ichnotaxon Cochlichnus anguineus as likely produced by larvae of members of the family Therevidae. Revision of members of the genus Prohercostomus from the Baltic amber is published by Grichanov (2026). Grichanov (2026) reports the discovery of a male of Medeterites latipennis from the Baltic amber, and provides a key to species belonging to the genus Medeterites. Men et al. (2026) describe first female of Palaeoglaesum sp. from mid-Cretaceous Burmese amber.
