About Pinkwinged Grasshopper
Pinkwinged Grasshopper (Atractomorpha sinensis) is a member of Pyrgomorphidae in the order Orthoptera. Its recorded origin status on Kauaʻi is introduced.
Pinkwinged Grasshopper (Atractomorpha sinensis) is documented from Kauaʻi. Pyrgomorphid grasshoppers are plant-feeding orthopterans with incomplete metamorphosis. On Kauaʻi, observations are most useful when they record host plant, nymph/adult, color phase, abundance and feeding damage. 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.
Pinkwinged Grasshopper (Atractomorpha sinensis) is an introduced plant-feeding grasshopper recorded on Kauaʻi. Green and gray adult color forms occur, and nymphs resemble smaller wingless adults.
Kauaʻi occurrence evidence: A 1992 Kapahi, Kauaʻi survey directly observed Atractomorpha sinensis; UH CTAHR reports it on all major Hawaiian islands.
The cited occurrence evidence does not by itself establish current abundance or population trend on Kauaʻi.
Life cycle
Egg; nymphal instars; adult; no pupa.
Habitat
Grasses, herbs, shrubs, agricultural land and disturbed vegetation.
Food and ecological role
Living plant foliage.
Reproduction
Eggs are deposited in soil or protected substrate; nymphs develop through successive molts.
Movement
Walking/jumping; adults may fly depending on species.
Ecosystem role
Herbivore and prey item.
Threats and impacts
Dense introduced populations can add herbivory to crops or vegetation.
Monitoring
Record host plant, nymph/adult, color phase, abundance and feeding damage.
