Hypocoena basistriga is a species of moth of the family Noctuidae first described by James Halliday McDunnough in 1933. [1] It is found from Newfoundland and Labrador west to British Columbia and Yukon. This species of moth is found to frequent mesic areas including the edges of aspen bluffs and hayfields, old fields, meadows, etc. [2]

Identification

This is a small (about 2.5–2.7 cm wingspan) dark red-brown or yellowish-brown moth. There is a black basal streak, short in some specimens but extending halfway across the wing in the fold in others. The most prominent markings are the contrasting white cubital and median veins, and to a lesser degree the anal and radial veins as well. For the most part this white scaling stops well short of the wing margin. The trailing edge of the forewing is usually pale yellow or buff. The hindwings are dark sooty brown or black. Sexes similar. The combination of small size, robust build, red-brown color and contrasting white cubital vein will usually identify this moth. [3]

History

Poorly known. No information is presently available regarding this species in the Pacific Northwest. It is expected to occur in bogs and other wetlands in northern British Columbia. [4] The adults are nocturnal and come to light. There is a single brood, which flies in mid-late summer. The larval host(s) is apparently unknown. Related species are borers in plant stems. [3]

Global distribution

Hypocoena basistriga is found in the western boreal zone, from Alaska to Alberta and the western Great Lakes region. It does not occur further east. Several records are shown for the Sierra Nevada in California.

Life cycle

Larvae

No information is presently available regarding the larval biology of this species. It bores in monocots like sedges (Cyperaceae); [4] perennial plants that resemble grasses, grow in shallow water or moist soils, and can reach 4 feet in height. [5]

Adult

This species has been collected in late summer and early fall across its range, most commonly during August and September. The limited number of records from British Columbia are from September and early October. It is nocturnal and comes to lights. [4] Adults' wingspan is 25–27 mm. Adults are on wing from mid to late summer. There is one generation per year.

<span class="mw-page-title-main">Erebidae</span> Family of moths

The Erebidae are a family of moths in the superfamily Noctuoidea. The family is among the largest families of moths by species count and contains a wide variety of well-known macromoth groups. The family includes the underwings (Catocala); litter moths (Herminiinae); tiger, lichen, and wasp moths (Arctiinae); tussock moths (Lymantriinae), including the arctic woolly bear moth ; fruit-piercing moths ; micronoctuoid moths (Micronoctuini); snout moths (Hypeninae); and zales, though many of these common names can also refer to moths outside the Erebidae. Some of the erebid moths are called owlets.

<i>Ichneutica nullifera</i> Species of moth

Ichneutica nullifera is a moth of the family Noctuidae. This species is endemic to New Zealand and can be found in the Tongariro National Park, along the Wellington coast and throughout the South Island. The adults are large and the forewing of adults can vary in colour from pale fawn to dark grey. The larvae are coloured a bright yellow-brown with a paler underside. The larval host species are in the genus Aciphylla and as a result the adult moths are often found in habitat dominated by species in this genus. Adults are on the wing from November to early April and are sometimes attracted to light.

<i>Ichneutica sulcana</i> Species of moth, endemic to New Zealand

Ichneutica sulcana, the dark underwing wainscot, is a moth of the family Noctuidae. It is endemic to New Zealand and can be found throughout the North, South and Stewart Islands at a range of altitudes from the lowlands to the alpine zone. This species prefers to live in native grass, shrub and wetland habitats as well as in native forest. The larval host plants of this species are forest grasses and sedges and larvae have been reared on Microlaena avenacea and species within the genus Carex. The larva pupates in the soil. Adults are on the wing from December to May but have also been recorded in August and September in the northern parts of the North Island. They are attracted to sugar traps as well as to light. I. sulcana and I. supersulcana are very similar in appearance but can be distinguished as there are differences in the male abdomen and genitalia of the two species. Also these two species do not appear to share a range as I. supersulcana seems to prefer to live at higher altitudes than I. sulcana. I. sulcana might also be confused with I. semivittata but I. sulcana is a larger species with a much darker abdomen and hindwing, and has only 1 to 3 dots on the forewing postmedian line.

<i>Ichneutica steropastis</i> Species of moth endemic to New Zealand

Ichneutica steropastis, or the flax notcher moth, is a species of moth in the family Noctuidae. It is endemic to New Zealand and can be found throughout the country from the Three Kings Islands to Stewart Island as well as in the Chatham Islands. The larvae of this species feed on a variety of native and introduced plants however the New Zealand flax is one of the more well known host plants for the larvae of this moth. The larvae are nocturnal, hiding away in the base of the plants and coming out to feed at night. They create a distinctive notch in the leaf when they feed. The adults of this species are on the wing from October to March. Although adult specimens of I. steropastis are relatively easy to recognise they might possibly be confused with I. inscripta, I. theobroma or with darker forms of I. arotis. However I. steropastis can be distinguished as it has a long dark basal forewing streak that these three species lack.

<i>Properigea albimacula</i> Species of moth

Properigea albimacula is a small to medium-sized moth in the family Noctuidae first described by William Barnes and James Halliday McDunnough in 1912. It is found in the western US on the slopes of Cascades north of Oregon and almost throughout California. The wingspan is about 15 mm. Adults fly during the summer and are most common during July. This species is nocturnal and comes to lights.

<i>Acleris ptychogrammos</i> Species of moth

It is found in North America, where it has been recorded from Alabama, British Columbia, Illinois, Indiana, Kentucky, Maine, Manitoba, Maryland, Massachusetts, Michigan, Mississippi, New Hampshire, New York, North Carolina, Ohio, Oklahoma, Ontario, West Virginia and Wisconsin.

<i>Ichneutica sapiens</i> Species of moth

Ichneutica sapiens is a moth of the family Noctuidae. This species is endemic to New Zealand. I. sapiens is found in the central North Island, in the South Island in Westland and also the southern parts of the South Island, and in Stewart Island. This species inhabits wetland habitat but its life history is unknown as are the host species of its larvae. The adult moths are on the wing between December and early January and are attracted to sugar traps and to light. I. sapiens is very similar in appearance to I. micrastra but is a smaller moth with a shorter wingspan, has differently formed antennae and slightly different forewing markings.

<i>Ichneutica infensa</i> Species of moth

Ichneutica infensa is a moth of the family Noctuidae. This species is endemic to New Zealand. It is found throughout the North and South Islands but appears to be rarely seen or collected in the north and west parts of the North Island. As at 2019 the northern limit to the range of this species is Titirangi. I. infensa inhabits tussock grasslands and native forest. Larvae are nocturnal and its host plants are in the genus Carex including Carex solandri. Larvae have also been raised on Bromus catharticus. Adults of this species are on the wing from late October to February. Adults are narrow winged with patterns on the forewings that are relatively distinctive. However this species can possibly be confused with I. inscripta.
