A Revolutionary Paleoindicator: Lepidoptera Scales

A Revolutionary Paleoindicator: Lepidoptera Scales

Moth scales, preserved in the mud of a coniferous forest lake, have been used to identify outbreaks of these insects over the past 10,000 years. This groundbreaking new technique, reported in the open-access journal Frontiers in Ecology and Evolution, can tell us more about the frequency and intensity of past and future insect epidemics, their impact on the forest environment and how they are linked to climate change.   […]

Cephalon, Cervix and Antennas

Cephalon, Cervix and Antennas

Head (Cephalon) Head in insects is in a solid capsule, as a result of coalescence of the six segments of embryonic: akron, antenaly, interkalary, mandibulary, maxillary, labialis. On his head are his lip components consisting of the upper lip (labrum), the lower lip (labium), the upper jaw (mandible) and lower jaw (maxilla). By analyzing embryonic development, it was concluded that all the lip parts except […]

Morphology of insects – The skin of insect

Morphology of insects – The skin of insect

Insect body is enveloped in a solid body shell – the skin, which in arthropods gives the body a constant shape and firmness, and presents an external skeleton. It’s composed of a number of articles, segments or wrists, which are made of thickened plates or sklerits. Boards are firmly connected to each other by elastic intersegment membranes. Physical segments are grouped into three regions: head […]
