An aedeagus is a reproductive organ of male arthropods through which they secrete sperm from the testes during copulation with a female. It can be thought of as the insect equivalent of a mammal's penis, though the comparison is fairly loose given the greater complexity of insect reproduction. The term is derived from Ancient Greek αἰδοῖα and ἀγός. It is pronounced or.

Ypthima huebneri, the common fourring, is a species of Satyrinae butterfly found in Asia.
Bacotoma is a genus of moths in the subfamily Spilomelinae of the family Crambidae. It currently comprises 11 species, with an Oriental and Australasian distribution ranging from India and Sri Lanka over China and Southeast Asia to Australia.
Chrysophyllis is a genus of the grass moth family (Crambidae). It is monotypic, containing the single species Chrysophyllis lucivaga. This moth is very little known, having only been recorded once, before 1935. It belongs to the large grass moth subfamily Spilomelinae; at the time of its description, these were still included in subfamily Pyraustinae and the entire Crambidae was then merged with the snout moths. While its exact relationships are undetermined, it is believed to be a close relative of Talanga. Like these, the male genitalia of C. lucivaga feature a remarkably elongated aedeagus shaped like a bullwhip.
Marasmianympha is a genus of moths of the grass moth family (Crambidae) described by Eugene G. Munroe in 1991. Its single species, Marasmianympha eupselias, was described by Edward Meyrick in 1929. Among the grass moths, it belongs to subfamily Spilomelinae. It is endemic to the Marquesas Islands of Polynesia, where it has been recorded on Fatu Hiva, Hiva Oa and Tahuata, but is suspected to occur on other islands as well. The holotype specimen is in the Natural History Museum, London.
Tessema sensilis is a little-known moth species, the only member of genus Tessema. It belongs to the grass moth family (Crambidae), and therein to the large subfamily Spilomelinae; at the time of its description, these were still included in subfamily Pyraustinae and the entire Crambidae was then merged with the snout moths. While its detailed relationships are undetermined, it may be a close relative of Herpetogramma and/or Pilocrocis.
Micropterix aglaella is a species of moth belonging to the family Micropterigidae.It is found in southern France, south-western Switzerland and northern Italy.
The external morphology of Lepidoptera is the physiological structure of the bodies of insects belonging to the order Lepidoptera, also known as butterflies and moths. Lepidoptera are distinguished from other orders by the presence of scales on the external parts of the body and appendages, especially the wings. Butterflies and moths vary in size from microlepidoptera only a few millimetres long, to a wingspan of many inches such as the Atlas moth. Comprising over 160,000 described species, the Lepidoptera possess variations of the basic body structure which has evolved to gain advantages in adaptation and distribution.
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, three pairs of legs, and mouthparts located outside of the head capsule. This position of the mouthparts divides them from their closest relatives, the non-insect hexapods, which include Protura, Diplura, and Collembola.
An intromittent organ is any external organ of a male organism that is specialized to deliver sperm during copulation. Intromittent organs are found most often in terrestrial species, as most non-mammalian aquatic species fertilize their eggs externally, although there are exceptions. For many species in the animal kingdom, the male intromittent organ is a hallmark characteristic of internal fertilization.
This glossary describes the terms used in formal descriptions of spiders; where applicable these terms are used in describing other arachnids.
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. The genitalia are attached onto the tenth or most distal segment of the abdomen. Lepidoptera have some of the most complex genital structures in the insect groups with a wide variety of complex spines, setae, scales and tufts in males, claspers of different shapes and different modifications of the ductus bursae in females.
Pebobs tetragramma is a moth of the family Cosmopterigidae. It is known from Guyana.
Cebrionini is a tribe of click beetles from the family Elateridae; formerly ranked as a subfamily or family, they are now considered a tribe within the subfamily Elaterinae.
Carabus insulicola is a species of black-colored beetle from the family Carabidae native to Japan. They are also known as ground beetles, and are oval shaped and elongated. They are black with a green metallic hue and vertical stripes running down their backs. The length of a fully grown beetle ranges from 27 to 31 mm. They have three pairs of legs and two pairs of wings. The outer wings are greatly degenerated, making them unable to fly. However, their relatively long legs allow them to walk and run fast. They have prominent mandibles that allow them to capture and eat prey.
Most insects reproduce oviparously, i.e. by laying eggs. The eggs are produced by the female in a pair of ovaries. Sperm, produced by the male in one testicle or more commonly two, is transmitted to the female during mating by means of external genitalia. The sperm is stored within the female in one or more spermathecae. At the time of fertilization, the eggs travel along oviducts to be fertilized by the sperm and are then expelled from the body ("laid"), in most cases via an ovipositor.
Phalonidia udana, or the loosestrife conch, is a European species of moth of the family Tortricidae, the subfamily Tortricinae, and the tribe Cochylini. It is widely distributed in the North Palaearctic but appears to be largely rare or missing in Central Europe. Previously, it was classified under the Phalonidia manniana taxon, but a recent effort to barcode all North European Lepidoptera revealed that P. udana and P. mannania are two distinct species.
Perothops is a genus of false click beetles in the family Eucnemidae containing 3 species. They are known as beech-tree beetles or perothopid beetles. They are small as they are only 10–18 millimeters long. It is the only genus in the monotypic subfamily Perothopinae. They are dark-colored beetles that are found across the United States, generally in forests. The genus was discovered by Johann Friedrich von Eschscholtz in 1836. It used to be considered a family not part of Eucnemidae. The genus's name is from Greek, translating to "maimed/crippled eye" or "eye of little necklaces/bands", referring to the placement of perothopid eyes.
