The shape and dimensions of the proboscis have evolved to give different species a wider and, therefore, more advantageous diet. [3] There is an allometric scaling relationship between body mass of Lepidoptera and length of proboscis [22] from which an interesting adaptive departure is the unusually long-tongued sphinx moth Xanthopan morganii ...
The main component of the male reproductive system is the testis, suspended in the body cavity by tracheae and the fat body. The more primitive apterygote insects have a single testis, and in some lepidopterans the two maturing testes are secondarily fused into one structure during the later stages of larval development, although the ducts ...
Butterfly antennal shapes, mainly clubbed, unlike those of moths. Drawn by C. T. Bingham, 1905. As in all insects, the body is divided into three sections: the head, thorax, and abdomen. The thorax is composed of three segments, each with a pair of legs.
Lepidoptera (/ ˌ l ɛ p ɪ ˈ d ɒ p t ər ə / LEP-ih-DOP-tər-ə) or lepidopterans is an order of winged insects which includes butterflies and moths.About 180,000 species of the Lepidoptera have been described, representing 10% of the total described species of living organisms, [1] [2] making it the second largest insect order (behind Coleoptera) with 126 families [3] and 46 superfamilies ...
The antennae always have two grooves on the underside; the club is variable in shape. Throughout the family, the front pair of legs in the male, and with three exceptions ( Libythea , Pseudergolis , and Calinaga ) in the female also, is reduced in size and functionally impotent; in some, the atrophy of the forelegs is considerable, e.g., the ...
The name "butterfly" comes from the shape of the data-flow diagram in the radix-2 case, as described below. [1] The earliest occurrence in print of the term is thought to be in a 1969 MIT technical report. [2] [3] The same structure can also be found in the Viterbi algorithm, used for finding the most likely sequence of hidden states.
The eggs are laid singly on a wide range of food plants including hedge mustard (Sisymbrium officinale), garlic mustard (Alliaria petiolata), cuckooflower (Cardamine pratense), water-cress (Rorippa nastutium-aquaticum), charlock (Sinapis arvensis), large bitter-cress (Cardamine amara), wild cabbage (Brassica oleracea), and wild radish (Raphanus raphanistrum), and so it is rarely a pest in ...
Anthocharis cardamines, the orange tip, is a butterfly in the family Pieridae, which contains about 1,100 species. A. cardamines is mainly found throughout Europe and temperate Asia [3] The males feature wings with a signature orange pigmentation, which is the origin of A. cardamines' common name.
