The evolutionary convergence of mid-Mesozoic lacewings and Cenozoic butterflies
Mid-Mesozoic kalligrammatid lacewings (Neuroptera) entered the fossil record 165 million years ago (Ma) and disappeared 45 Ma later. Extant papilionoid butterflies (Lepidoptera) probably originated 80-70 Ma, long after kalligrammatids became extinct. Although poor preservation of kalligrammatid fossils previously prevented their detailed morphological and ecological characterization, we examine...
متن کاملEarly Morphological Specialization for Insect-Spider Associations in Mesozoic Lacewings
Insects exhibit a wide diversity of anatomical specializations in their adult and immature stages associated with particular aspects of their biology. The order Neuroptera (lacewings, antlions, and their relatives) are a moderately diverse lineage of principally predatory animals, at least in their immature stages, as all have a modified piercing-sucking mandible-maxillary complex that allows t...
متن کاملMid-Mesozoic Flea-like Ectoparasites of Feathered or Haired Vertebrates
Parasite-host associations among insects and mammals or birds are well attended by neontological studies [1]. An Eocene bird louse compression fossil [2, 3] and several flea specimens from Eocene and Oligocene ambers [4-8], reported to date, are exceptionally similar to living louse and flea taxa. But the origin, morphology, and early evolution of parasites and their associations with hosts are...
متن کاملNew long-proboscid lacewings of the mid-Cretaceous provide insights into ancient plant-pollinator interactions
Many insects with long-proboscid mouthparts are among the pollinators of seed plants. Several cases of the long-proboscid pollination mode are known between fossil insects (e.g., true flies, scorpionflies, and lacewings) and various extinct gymnosperm lineages, beginning in the Early Permian and increasing during the Middle Jurassic to Early Cretaceous. However, details on the morphology of lac...
متن کاملEmbodiment , Language , and Mimesis
The present focus on embodiment in cognitive science undervalues concepts such as convention/norm, representation and consciousness. I argue that these concepts constitute essential properties of language, and this makes it problematic for “embodiment theories” to account for human language and cognition. These difficulties are illustrated by examining a particular, highly influential approach ...
