Drosophila differens is an endangered species of Hawaiian fly in the family Drosophilidae. This species is a member of the planitiba subgroup of the picture-wing clade of Hawaiian Drosophila. [2] It is found on the island of Molokai.
Drosophila differens was described by D. Elmo Hardy and Kenneth Y. Kaneshiro in 1975. [4] This fly is very similar to its Maui relative, D. planitibia , though most individuals of D. differens has a yellow face while D. planitibia have a black face. [4] However, Hardy and Kaneshiro report that it is difficult to find any consistently distinguishing character. These two species are capable of hybridizing, but crosses in both directions produce sterile males.
D. differens is larger than many other picture-wing species. [3] It is reported to breed in the rotting bark of Clermontia species. [5]
Drosophila hemipeza was listed as federally endangered in 2006 along with ten other species of picture-wing Drosophila. [3] Threats to the conservation of D. hemipeza include loss-of-habitat, in part due to invasive pigs and rats, as well as introduced predators such as yellowjacket wasps. Invasive plants such as Psidium cattleianum also threaten the conservation of D. differens by overwhelming native species and outcompete them for access to light. On Molokai, non-native axis deer threaten native ecosystems by trampling and overgrazing native plants.
The ʻiʻiwi or scarlet honeycreeper is a species of Hawaiian honeycreeper. The ʻiʻiwi is a highly recognizable symbol of Hawaiʻi. The ʻiʻiwi is the third most common native land bird in the Hawaiian Islands.
The Drosophilidae are a diverse, cosmopolitan family of flies, which includes species called fruit flies, although they are more accurately referred to as vinegar or pomace flies. Another distantly related family of flies, Tephritidae, are true fruit flies because they are frugivorous, and include apple maggot flies and many pests. The best known species of the Drosophilidae is Drosophila melanogaster, within the genus Drosophila, also called the "fruit fly." Drosophila melanogaster is used extensively for studies concerning genetics, development, physiology, ecology and behaviour. Many fundamental biological mechanisms were discovered first in D. melanogaster. The fruit fly is mostly composed of post-mitotic cells, has a very short lifespan, and shows gradual aging. As in other species, temperature influences the life history of the animal. Several genes have been identified that can be manipulated to extend the lifespan of these insects. Additionally, Drosophila subobscura, also within the genus Drosophila, has been reputed as a model organism for evolutionary-biological studies, along with D. sechellia for the evolution of host specialization on the toxic noni fruit and Scaptomyza flava for the evolution of herbivory and specialist on toxic mustard leaves.
The Kauaʻi cave wolf spider, also known to local residents as the blind spider, is only known to occur in a few caves in a lava flow with an area of 10.5 km2 (4.1 sq mi) in the Kōloa–Poʻipū region of Kauaʻi, Hawaiian Islands, and only six populations are known to exist. While their nearest surface-dwelling relatives have large eyes, this species has completely lost its eyes. They reach a body length around 20 mm (0.8 in), and are reddish brown and completely harmless to people. Unlike most wolf spiders, it produces only 15 to 30 eggs per clutch. The female carries the egg sac in her mouthparts until the spiderlings hatch.
The kākāwahie or Molokaʻi creeper is an extinct species of Hawaiian honeycreeper. It was found on the Hawaiian island of Molokaʻi in Hawaii.
The Pacific Hawaiian damselfly, Megalagrion pacificum, is a species of damselfly that is native to Hawaiian streams and wetlands at low elevations. They are predaceous and territorial narrow-winged damselflies that can be identified by their abdominal markings. In the last century, the populations of Pacific Hawaiian damselflies have decreased due to invasive species, habitat loss, climate change, stream alteration, and urban development. The species was listed as an endangered species under the Endangered Species Act on July 26, 2010.

Drosophila silvestris is a large species of fly in the family Drosophilidae that are primarily black with yellow spots. As a rare species of fruit fly endemic to Hawaii, the fly often experiences reproductive isolation. Despite barriers in nature, D. silvestris is able to breed with D. heteroneura to create hybrid flies in the laboratory.
The Hawaiian Drosophilidae are a lineage of flies within the genus Drosophila. This monophyletic clade includes all of the endemic Hawaiian Drosophila and all members of the genus Scaptomyza, which contains both Hawaiian and non-Hawaiian species. The Hawaiian Drosophilidae are descended from a common ancestor estimated to have lived 25 million years ago. Species of Hawaiian Drosophilidae flies have been studied as models of speciation and behavioral evolution. Along with other members of the native Hawaiian ecosystem, the conservations status of many species of Hawaiian Drosophilidae is threatened by habitat loss and introduced predators, among other factors.
Drosophila hemipeza is an endangered species of Hawaiian fly in the family Drosophilidae. This species is a member of the planitiba subgroup of the picture-wing clade of Hawaiian Drosophila.
Drosophila aglaia is an endangered species of fly from Hawaii. This species is a member of the aglaia subgroup of the picture-wing clade of Hawaiian Drosophilidae. It is only found on the island of Oahu, and has not been observed since 1997, when it was found in Palikea.
Drosophila heteroneura is an endangered species of Hawaiian fly in the family Drosophilidae. This rare fly is part of the Hawaiian Drosophila lineage, and is only found in mesic and wet forests on the island of Hawaii.
Drosophila montgomeryi is an endangered species of fly from the lineage of Hawaiian Drosophilidae. It is found on the island of Oahu.
Drosophila tarphytrichia is an endangered species of fly from Hawaii, in the species rich lineage of Hawaiian Drosophilidae. It is only found on the island of Oahu. While originally collected near Manoa Falls in 1949, this fly is thought to have been extirpated from the Koʻolau Range and now only found in the Waiʻanae Range. This species is a member of the lanaiensis subgroup in the picture-wing clade.
Drosophila musaphilia is an endangered species of fly from Hawaii, in the species rich lineage of Hawaiian Drosophilidae. It is only found on the island of Kauai. The last reported sighting of this species was in 1988.
Drosophila neoclavisetae is an endangered species of fly from Hawaii, in the species rich lineage of Hawaiian Drosophilidae. It is only found in West Maui. It can be distinguished from its East Maui counterpart, D. clavisetae, by the shape of the long hairs on the abdomen, which are more rounded in D. neoclavisetae and more flattened in D. clavisetae.
Drosophila obatai is an endangered species of fly from Hawaii, in the species rich lineage of Hawaiian Drosophilidae. It is only found on the island of Oahu. D. obatai is part of the orphnopeza subgroup in the picture-wing clade, and is closely related to D. sodomae, a fly found on the islands of Maui and Molokai.
Drosophila ochrobasis is an endangered species of fly from Hawaii, in the species rich lineage of Hawaiian Drosophilidae. It is found on the Big island of Hawaii, and has historically been recorded from four of the five volcanoes, though it is now largely absent from most of those sites. This species is in the adiastola subgroup and is closely related to D. setosimentum, but male D. ochrobasis have strikingly different wing markings.
Drosophila substenoptera is an endangered species of fly in the species rich lineage of Hawaiian Drosophilidae. It is only found on the island of Oahu,. Historically it was collected throughout the Ko'olau and Wai'anae ranges, but now is only known to occur near the summit of Mt. Kaala. D. substenoptera is a member of the planitibia species group and neopicta subgroup within the picture-wing clade.

Phyllostegia haliakalae, commonly known as the Haliakala phyllostegia, is a species of flowering plant in the mint family, Lamiaceae. It was described by Heinrich Wawra von Fernsee in 1872. The species Latin name derives from the Hawaiian word, "haliakala", which means "happy".
