LeptocorisLeptocoris mitellatus Leptocoris tagalicus

Leptocoris tagalicus are commonly known as the Australia Soapberry Bugs or the Red Eyes Bug. They are part of the cosmopolitan family of coreoid bugs (family Rhopalidae) that include the Lepticoris spp, that are seed-eating predators of Australian plants.

They are between 9 to 13 mm in length, and are usually purplish-red or brick red, although some obervations include ochre or dark brown. The colour variation may be a regional thing. The membrane and appendages are dark brown or black.

Current observations (on Atlas of Living Australia) have Leptocoris tagalicus across mainland Australia, with most sightings in Central Australia, and along the east coast from Queensland down through New South Wales.

They can often be mistaken for Leptocoris mitellatus, with some references alluding to Leptocoris tagalicus are usually found on plants, whilst Leptocoris mitellatus are often found on the ground.

Whilst they are considered seed-eating predators, the following photographs from Alice Springs in the Northern Territory, are of the Leptocoris tagalicus feeding on the nectar from the Needlewood (Hakea leucoptera).
