Caterpillars are the larval stage of members of the order Lepidoptera.
A larva is a distinct juvenile form many animals undergo before metamorphosis into adults. Animals with indirect development such as insects, amphibians, or cnidarians typically have a larval phase of their life cycle.
A pupa is the life stage of some insects undergoing transformation between immature and mature stages. Insects that go through a pupal stage are holometabolous: they go through four distinct stages in their life cycle, the stages thereof being egg, larva, pupa, and imago. The processes of entering and completing the pupal stage are controlled by the insect's hormones, especially juvenile hormone, prothoracicotropic hormone, and ecdysone. The act of becoming a pupa is called pupation, and the act of emerging from the pupal case is called eclosion or emergence.
Eupithecia is the largest genus of moths of the family Geometridae, and the namesake and type genus of tribe Eupitheciini. Species in the genus are, like those of other genera in the tribe, commonly known as pugs. The genus is highly speciose, with over 1400 species, and members of the genus are present in most of the world with exception of Australasia. Roughly a quarter of described Eupithecia species occur in the Neotropical realm, where they have an especially high species diversity in the montane rain forests of the Andes. The genus includes a few agricultural pest species, such as the currant pug moth, Eupithecia assimilata, which is a pest on hops, and the cloaked pug moth, Eupithecia abietaria, which is a cone pest in spruce seed orchards.
The tawny speckled pug is a moth of the family Geometridae.
The goldenrod pug is a moth of the family Geometridae. The species was first described by Henry Doubleday in 1861. It is found throughout the Palearctic region. In the British Isles it is widespread but rather locally distributed.
The eastern tent caterpillar is a species of moth in the family Lasiocampidae, the tent caterpillars or lappet moths. It is univoltine, producing one generation per year. It is a tent caterpillar, a social species that forms communal nests in the branches of trees. It is sometimes confused with the gypsy moth and the fall webworm, and may be erroneously referred to as a bagworm, which is the common name applied to unrelated caterpillars in the family Psychidae. The moths oviposit almost exclusively on trees in the plant family Rosaceae, particularly cherry (Prunus) and apple (Malus). The caterpillars are hairy with areas of blue, white, black and orange. The blue and white colors are structural colors created by the selective filtering of light by microtubules that arise on the cuticle.
Notodontidae is a family of moths with approximately 3,800 known species. The family was described by James Francis Stephens in 1829. Moths of this family are found in all parts of the world, but they are most concentrated in tropical areas, especially in the New World.
The garden tiger moth or great tiger moth is a moth of the family Erebidae. Arctia caja is a northern species found in the US, Canada, and Europe. The moth prefers cold climates with temperate seasonality, as the larvae overwinter, and preferentially chooses host plants that produce pyrrolizidine alkaloids. However, garden tiger moths are generalists, and will pick many different plants to use as larval host plants.
Eupithecia innotata, the angle-barred pug, is a moth of the family Geometridae. The species was first described by Johann Siegfried Hufnagel in 1767. It ranges from Spain in the west to western Siberia and Central Asia in the east.
Eriogaster lanestris, commonly known as the small eggar, is a moth of the family Lasiocampidae that is found across the Palearctic. Unlike many other members of the Lasiocampidae, the small eggar is a social insect. Historically, only eusocial insects like ants, bees, and termites were thought to exhibit complex social organization and communication systems. However, research since the late 20th century has found that E. lanestris, among a number of other phylogenetically related moth and butterfly species, demonstrates social behaviors as well. Larvae spend nearly their entire development in colonies of about 200 individuals, and this grouped social structure offers a number of benefits, from thermoregulation to increased foraging success.
Eupithecia tantillaria, the dwarf pug, is a moth of the family Geometridae. It was described by Jean Baptiste Boisduval in 1840. The species can be found in the Palearctic realm.
Eupithecia nanata, the narrow-winged pug, is a moth of the family Geometridae. The species was first described by Jacob Hübner in 1813. It can be found all over Europe including Russia and Ukraine. In the Alps it occurs up to 2,200 metres (7,200 ft) above sea level and in the Pyrenees to 2400 meters. The species prefers dry or boggy heathlands.
Eupithecia tripunctaria, the white-spotted pug, is a moth of the family Geometridae. The species can be found from Europe to Korea and Japan and in North America.
Eupithecia rhodopyra is a moth of the family Geometridae. It was first described by Edward Meyrick in 1899. It is endemic to the Hawaiian island of Kauai.
Omiodes antidoxa is a moth of the family Crambidae. It is endemic to the Hawaiian islands of Kauai and Oahu.
Eupithecia pygmaeata, the marsh pug, is a moth of the family Geometridae. It is known from most of Europe, western and southern Siberia, the Russian Far East, northern Mongolia and North America .The species primarily colonizes floodplain and disused forests, bogs, river banks and marshy meadows. E. pygmaeata reaches up to 1800 meters in South Tyrol.
Hyposmocoma carnivora is a species of moth of the family Cosmopterigidae. It is endemic to Hawaii.
Hyposmocoma pupumoehewa is a species of moth of the family Cosmopterigidae. It is endemic to Maui.
Eupithecia distinctaria, the thyme pug, is a moth of the family Geometridae. It is found throughout Europe. It is also found in Iran. from the Iberian Peninsula through western and central Europe including the British Isles as well as further east as far east as far as Russia and Iran. In the north the range reaches as far as the southern Fennoscandia, to the south, where it is more common, it occupies the Mediterranean and Asia Minor. It is found primarily on warm, stony slopes and rocky structures as well as on sparse grassy areas with thyme mounds. In the Alps, it rises to heights of 2000 metres.
