• Acanthopodous — A scholarly morphological term used as an adjective to describe an organism, arthropod, or anatomical structure whose limbs, legs, or locomotory appendages are equipped with spines, rigid thorns, or rows of sharp spikes. As a masculine noun, it defines a locomotory limb structurally modified through the development of such prickly elements, an adaptation found in certain predatory insects (such as some mantis or orthopteran species) used for efficiently capturing and immobilizing prey.
• Acaricide — A chemical substance, biological preparation, or drug specifically designed to kill mites and ticks and to arrest the multiplication or development of their eggs and larvae. In phytopharmacy, it is deployed as a protective pesticide for crops against spider mites, whereas in human and veterinary medicine, it serves as a topical antiparasitic lotion to eradicate ectoparasites causing scabies or tick infestations.
• Adephagan — A term describing or belonging to a group of predominantly predatory coleopteran insects, characterized by legs adapted for running, mouthparts shaped for tearing prey, and an exclusively carnivorous or voracious diet. As a noun, it designates any specimen representing this suborder (Adephaga), known for its active ecological role in controlling other invertebrate populations.
• Air-dwelling — Living, developing, or carrying out biological activity in the air or aerial environment; a rare term used in ecology to classify organisms, insects, or microorganisms that structurally depend on the free atmosphere for movement or reproduction, as opposed to terrestrial, aquatic, or cavernicolous ones.
• Aphagous — A biological term used to describe an organism or animal that, during a specific stage of its life cycle or biological development, does not feed at all. The phenomenon is frequently encountered among certain insects in their adult (imago) or pupal stage, where the mouthparts are atrophied, their exclusive function being reproduction, with energy provided by reserves accumulated during previous larval phases.
• Aphanipteran — A small, wingless parasitic insect in its adult stage, structurally adapted for jumping and hematophagous feeding (blood-sucking), belonging to the order Aphaniptera (also known scientifically as Siphonaptera), which includes fleas. Their bodies are laterally flattened, protected by a rigid chitinous exoskeleton, and equipped with highly developed hind legs designed for executing expansive leaps onto host organisms.
• Aphidian — Pertaining to aphids or the aphid group; characteristic of sap-sucking insects from the Aphidoidea superfamily. As a plural noun (afidieni), it denotes this systematic group of phytophagous insects.
• Aftidor — Proprietary commercial name of a phytosanitary product widely used in agriculture, formulated as a highly efficient systemic insecticide. Its active substance acts through contact and ingestion against a broad spectrum of pests attacking vegetable, fruit tree, or cereal crops, protecting the cellular structure of treated plants.
• Coenagrionid damselfly — A small, slender-bodied damselfly belonging to the family Coenagrionidae (formerly Agrionidae), structurally characterized by transparent membranous wings folded vertically over the abdomen at rest and often displaying brilliant metallic coloration. These insects are predators, inhabiting areas in close proximity to freshwater lentic or lotic aquatic systems.
• Locust — A rare regional name or popular phonetic variant documented in certain dialects for the noun 'lăcustă' (locust/grasshopper); an orthopteran insect harmful to agriculture, with long hind legs adapted for jumping and a chewing mouth apparatus, structurally renowned for its migrations in devastating swarms. This popular archaism preserves a special ethno-entomological value, recorded in linguistic questionnaires dedicated to traditional fauna names.
• Cabbage white — A popular name given to several species of diurnal butterflies from the Pieridae family, having white wings sprinkled with black or grey spots, whose caterpillar is a highly dangerous pest for cabbage crops and other crucifers.
• Carpenter bee — A popular name attributed to the bumblebee or carpenter bees of the genus Xylocopa, characterized by a massive, robust body of a shiny-black or dark-violet color, with opaque wings and a deep buzz, which build their nests by burrowing tunnels into the dry wood of rural structures.
• Bumblebee — A popular name given to the bumblebee or to certain species of large flies, horseflies, or solitary ground wasps, characterized by a darker, blackish or coppery coloration and a loud buzzing sound, which vaguely resemble bees but do not produce honey.
• Bee-eater — A small insectivorous migratory bird of the order Coraciiformes, with an extremely brightly colored plumage in shades of blue, green, yellow, and coppery, characterized by a long, sharp, and slightly curved bill, which feeds predominantly on bees, bumblebees, and other insects caught in flight.
• Apiary — A specially arranged place where beehives are located and bees are raised; an apiary or beeyard; the occupation or craft of beekeeping, including the totality of knowledge and techniques needed for their exploitation. Collectively, it can designate a large mass of moving bees.
• Bee-eater — A popular or regional name attributed to the European bee-eater bird (albinărel) or to a small variety of white butterfly (albiliță); a small insectivorous bird recognized for hunting bees near apiaries.
• Aldrin — A surname of Germanic or Anglo-Saxon origin, famous due to the American astronaut Buzz Aldrin (b. 1930), the second man to walk on the Moon during the Apollo 11 mission. In the chemical industry and ecotoxicology, the lowercase term (aldrin) designates a highly toxic organochlorine insecticide, banned globally under the Stockholm Convention due to its heavy structural persistence in the environment.
• Alates — A specialized term used in entomology or biology to designate insects that are in their adult, winged, and sexually mature stage, particularly regarding ant or termite species that develop wings exclusively for the nuptial mating flight. It is a Romanian adaptation of the international scientific concept.
• Amathusia — A genus of large butterflies within the Nymphalidae family (subfamily Morphinae), native to the tropical regions of Southeast Asia, commonly known as palmkings. They feature large wings with cryptic undersides mimicking dead leaves.
• Ametabolous insect — An insect belonging to the group characterized by the absence of metamorphosis (Ametabola), in which the juvenile form (nymph) structurally resembles the adult almost perfectly, differing only in body size and the developmental stage of the reproductive system. As an adjective, it describes a species, a larva, or a direct biological development, characteristic of lower apterygote insects, such as the silverfish (Lepisma saccharina) or the order Thysanura.
