Chromosome number evolution in skippers (Lepidoptera, Hesperiidae)
Lepidoptera (butterflies and moths), as many other groups of animals and plants, simultaneously represent preservation of ancestral karyotype in the majority of families with a high degree of chromosome number instability in numerous independently evolved phylogenetic lineages. However, the pattern and trends of karyotype evolution in some Lepidoptera families are poorly studied. Here I provide...
متن کاملCycles of F - actin redistribution in the dermal glands of an insect relate to secretion
Cells of the dermal glands in Calpodes ethlius Stoll (Lepidoptera, Hesperiidae) survive without division but increase in size from moult to moult. The secretory cells become especially large, measuring up to 6 mm long in the fifth larval stadium. The nucleus in these giant cells has a sponge-like profile, with the nuclear envelope indented around cytoplasmic intrusions, each of which comes to c...
متن کاملGenesis of Mitochondria in Insect Fat Body
Electron microscopy and stereological methods have been used to study the time course and mechanism of mitochondrial genesis in the adult fat body of Calpodes ethlius, (Lepidoptera, Hesperiidae). Most of the larval mitochondria are destroyed during a phase of autolysis shortly before pupation, so that pupal and early adult fat body cells have few mitochondria. The number of mitochondria per cel...
متن کاملEvolution of extreme proboscis lengths in Neotropical Hesperiidae (Lepidoptera)
Exaggerated morphologies have evolved in insects as adaptations to nectar feeding by natural selection. For example, the suctorial mouthparts of butterflies enable these insects to gain access to floral nectar concealed inside deep floral tubes. Proboscis length in Lepidoptera is known to scale with body size, but whether extreme absolute proboscis lengths of nectar feeding butterflies result f...
متن کاملL-Glutamate retrieved with the moulting fluid is processed by a glutamine synthetase in the pupal midgut of Calpodes ethlius.
From apolysis until pupal ecdysis, the pharate pupa of the Brazilian Skipper (Calpodes ethlius) lies wrapped in a prepupal shell composed of the larval cuticle and an ecdysial space (ES) filled with enzyme-rich moulting fluid (MF). In the 4h before ecdysis the pharate pupa drinks the moulting fluid through its mouth and anus, and transfers the cuticular degradation products to its midgut (MG). ...
