About Mestolobes orthrias
Mestolobes orthrias is a member of Crambidae in the order Lepidoptera. Its recorded origin status on Kauaʻi is endemic — kauaʻi.
Mestolobes orthrias (Mestolobes orthrias) is documented from Kauaʻi. Crambid moths undergo complete metamorphosis. Caterpillars often feed on leaves, stems, grasses, or aquatic plants, while adults are winged and usually short-lived relative to the larval stage. On Kauaʻi, observations are most useful when they record larval host, feeding shelter/mine/roll, adult flight period, parasitoids, and stage-specific photographs. Where island-specific host, prey, breeding-site, abundance, or seasonal information is not yet firmly documented, those details should remain tied to direct specimens and field observations rather than inferred from populations elsewhere.
Mestolobes orthrias is a Kauaʻi-endemic crambid moth documented from historical montane collections in the Kaholuamano/Waimea region.
Kauaʻi occurrence evidence: Fauna Hawaiiensis records M. orthrias from Kaholuamano and the Waimea mountains on Kauaʻi.
The cited occurrence evidence does not by itself establish current abundance or population trend on Kauaʻi.
Life cycle
Egg; caterpillar; pupa; adult.
Habitat
Host vegetation; larval microhabitat is species-specific.
Food and ecological role
Larval host plants are species-specific; adults generally use nectar or do not feed extensively.
Reproduction
Adults mate and females lay eggs on or near larval host plants.
Movement
Adults fly; larvae move locally among host tissues or leaves.
Ecosystem role
Herbivore as a larva and prey item across life stages; some species are crop pests while others are endemic specialists.
Threats and impacts
Native species can be sensitive to host-plant loss and introduced parasitoids; introduced species can damage crops.
Monitoring
Record larval host, feeding shelter/mine/roll, adult flight period, parasitoids, and stage-specific photographs.
