Hyposmocoma papaiili Schmitz & Rubinoff

Crab Shell Cosmet Moth (Hyposmocoma papaiili)

The Crab Shell Cosmet Moth was scientifically described in the year 2011.

It is a rather inconspicuous dark greyish brown colored species, which is restricted to the island of Maui.

the males have a wingspan of about 0,72 to 0,88 cm, the females of up to 1,26 cm.

The larvae were found on Eucalyptus trees (which are not native to the Hawaiian Islands), where they most probably feed on lichens.

The larval case in its shape resembles somewhat the carapace of a crab. It is about 1 cm long and has an entrance at each of the both, strangely serrated ends.

Hyposmocoma eliai Schmitz & Rubinoff

Elia’s Cosmet Moth (Hyposmocoma eliai)

This species was described in the year 2011, it is so far known only from the type locality near the Nawiliwili bay in the southeast of the island of Kaua’i.

It is one of the smallest species of its genus, males have a wingspan of only about 0,45 to 0,5 cm. The color of the forewings is blackish, except for three disconnected white stripes on each of the wings, and some dark grey scales, the hindwings are completely grey in color.

The larvae live on large barren volcanic rocks along the shoreline, which regularly getting sprayed with salty sea water. They build a bag-shaped, about 0,4 cm long larval case, made of fine sand interwoven with silk.

They obviously feed on algae. [1]

Hyposmocoma moopalikea Schmitz & Rubinoff

Palikea Water Cosmet Moth (Hyposmocoma moopalikea)

The Palikea Water Cosmet Moth was described in the year 2011.

The species is endemic to the island of Maui, it is so far known only from the vicinity of the Palikea stream in the Kipahulu valley.

The case-bearing caterpillars are aquatic, the larval cases are burrito-shaped and 0,5 to 0,7 cm in length.

The male moth reaches a wingspan of about 1 cm, the female is slightly larger. The forewings are mostly dark brown with some scattered off-white scales. [1]

~~~

The Palikea Water Cosmet Moth appears to be very rare. [1]

Hyposmocoma domicolens (Butler)

House-dwelling Cosmet Moth (Hyposmocoma domicolens)

This species was described already in 1881, the type specimen was collected in a house – thus its species epithet.

The adult reaches a wingspan of about 1,3 cm.

The species is so far known only from the Makawao Forest Reserve, a habitat that is now rapidly declining due to damage from invasive ungulates. [1][2]

~~~

There are several specimens from other islands (Hawai’i, Lana’i, and Moloka’i), that were erroneously assigned to this species. [1]

Hyposmocoma eepawai Schmitz & Rubinoff

Eepa’s Water Cosmet Moth (Hyposmocoma eepawai)

This species was described in the year 2011.

The species is endemic to the island of Kaua’i, where it is known only from the drainage of the Kawaikoi stream on the north-western plateau of the Alaka’i swamp.

The amphibious caterpillars build bugle-shaped larval cases.

The moth reaches a wingspan of up to 1,6 cm, the forewings are mostly greyish-blue with pale tipped scales, with very few scattered rusty scales. [1]

Hyposmocoma tetraonella (Walsingham)

Tetraonella Cosmet Moth (Hyposmocoma tetraonella)

This species, which has been scientifically described in the year 1907, was found in the Kona region on the island of Hawai’i at an elevation of about 1200 m.

The biology of this species is completely unknown so far.

Hyposmocoma opuulaau Schmitz & Rubinoff

Tree Cone Cosmet Moth (Hyposmocoma opuulaau)

This species from the island of Maui was described in the year 2011.

The larval case of this species is a small and thin, elongate cone-shaped, up to 0,9 cm long structure, and is decorated with very small bits of sand and dried plant pieces which are woven with silk filaments on the dorsal half of the case. The case is bicolored, being pale gray to silvery on the ventral side. It furthermore has an operculum which can be closed by the larva from the inside.

The larvae were found on and beneath the bark of Swamp Mahagony trees (Eucalyptus robusta Sm.), a tree species that is not native to the Hawaiian Islands, and that was only introduced by men. They most probably feed on algae and lichens, crowing on the bark.

The adult moths have very dark grey to nearly black colored forewings, the hindwings are a shade lighter.

They have a wingspan of 0,7 to about 1 cm.

Hyposmocoma pukoa Schmitz & Rubinoff

Koa Bugle Cosmet Moth (Hyposmocoma pukoa)

The Koa Bugle Cosmet Moth was scientifically described in the year 2011. This species is so far known from the Makawao Forest Reserve only, where its larvae can be found on Koa Acacias (Acacia koa A. Gray).

As in all Hyposmocoma species, the larvae live in a larval case. This larval case is a bugle-shaped structure, and about 0,4 to 0,7 cm in length. Its color is a light grey with several darker bands, representing somewhat like growth rings that show the different periods during which the larva has expanded its case.

The adult moths are light grey in color, and display some inconspicuous, darker markings on their forewings.

The males have a wingspan of about 0,9 to 1 cm, the females are slightly larger than the males.
