Polyphaga is the largest and most diverse suborder of beetles. It comprises 144 families in 16 superfamilies, and displays an enormous variety of specialization and adaptation, with over 350,000 described species, or approximately 90% of the beetle species discovered thus far. Key characteristics of Polyphaga are that the hind coxa (base of the ...
Insect physiology includes the physiology and biochemistry of insect organ systems. [ 1] Although diverse, insects are quite similar in overall design, internally and externally. The insect is made up of three main body regions (tagmata), the head, thorax and abdomen. The head comprises six fused segments with compound eyes, ocelli, antennae ...

Oligophagy refers to the eating of only a few specific foods, and to monophagy when restricted to a single food source. [1] The term is usually associated with insect dietary behaviour. [2] Organisms may exhibit narrow or specific oligophagy where the diet is restricted to a very few foods or broad oligophagy where the organism feeds on a wide ...
Insect morphology is the study and description of the physical form of insects. The terminology used to describe insects is similar to that used for other arthropods due to their shared evolutionary history. Three physical features separate insects from other arthropods: they have a body divided into three regions (called tagmata) (head, thorax ...
the part of the antenna distal to the pedicel composed of one or more segments, called flagellomeres. (Anatomical feature) the posterior opening of the head capsule, covered by the cervix. (Anatomical feature) the pair of wings of a four-winged insect closest to the head. small, pit-like structure in the exoskeleton.
Antheraea polyphemus, the Polyphemus moth, is a North American member of the family Saturniidae, the giant silk moths. It is a tan-colored moth, with an average wingspan of 15 cm (6 in). The most notable feature of the moth is its large, purplish eyespots on its two hindwings. The eyespots give it its name – from the Greek myth of the cyclops ...
