Male genitalia of Lepidoptera Female genitalia of Lepidoptera. The study of the genitalia of Lepidoptera is important for Lepidoptera taxonomy in addition to development, anatomy and natural history. The genitalia are complex and provide the basis for species discrimination in most families and also in family identification. [1]
Male genitalia of Lepidoptera Female genitalia of Lepidoptera. The genitalia are complex and provide the basis for species discrimination in most families and also in family identification. [7] The genitalia arise from the tenth or most distal segment of the abdomen.
Male genitalia of Lepidoptera. The main component of the male reproductive system is the testicle, 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 leading from them ...
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 ...
For terms see External morphology of Lepidoptera. recto (top) and verso of male. The wingspan is 75–80 mm in males and 75–85 mm in females. Both wings beneath without distinct dark longitudinal streaks on the folds between the veins and without dark longitudinal streaks in the cell of the hindwing. Both wings with submarginal spots.
The male passes a spermatophore to the female; to reduce sperm competition, he may cover her with his scent, or in some species such as the Apollos plugs her genital opening to prevent her from mating again. [40] The vast majority of butterflies have a four-stage life cycle: egg, larva (caterpillar), pupa (chrysalis) and imago (adult).
A gynandromorph can have bilateral symmetry—one side female and one side male. [24] Alternatively, the distribution of male and female tissue can be more haphazard. Bilateral gynandromorphy arises very early in development, typically when the organism has between 8 and 64 cells. [25] Later stages produce a more random pattern. [citation needed]
Reaching approximately 1 inch (2.5 cm) in length, male fiery skippers are orange or yellow while the females are dark brown. Small brown spots may be observed on both the hindwing and forewing of both sexes although to a varying degree. Females may be darker brown overall with pale checkered markings on the hindwing.
