Insects comprise over half of all described animal species. Together with the Protura
(coneheads), Collembola (springtails) and Diplura (two-pronged bristletails), insects form …

Abstract The Jehol Biota is an Early Cretaceous terrestrial fossil assemblage of paramount
significance, and its core distribution areas are western Liaoning, northern Hebei, and …

Ticks are currently among the most prevalent blood-feeding ectoparasites, but their feeding
habits and hosts in deep time have long remained speculative. Here, we report direct and …

Abstract Fossils from the “Jehol Biota” have been studied for nearly 90 years, and the term
“Jehol Biota” has been extensively used and is well known today, largely thanks to the …

Phthirapteran lice (true lice or parasitic lice) are a major group of ectoparasitic insects living
on their bird or mammal hosts during their entire life cycle. 1 Due to their highly specialized …

The study of the Early Cretaceous terrestrial Jehol Biota, which provides a rare window for
reconstruction of a Lower Cretaceous terrestrial ecosystem, is reviewed with a focus on …

Insect parasites and parasitoids are a major component of terrestrial food webs. For
parasitoids, categorization is whether feeding activity is located inside or outside its host, if …

During the past 20 years, more than 1,600 species of well-preserved fossil insects, including
members of over 270 families within 24 orders, have been described from the Middle …

Fleas (order Siphonaptera) are highly-specialized, diverse blood-feeding ectoparasites of
mammals and birds with an enigmatic evolutionary history and obscure origin. We here …

The mouthparts of insects are a phenomenal example of a multi-element, modular, feeding
apparatus that repeatedly has been modified structurally to perform every feeding function …
