Like all Australian robins, the eastern yellow robin tends to inhabit fairly dark, shaded locations, and is a perch and pounce hunter, typically from a tree trunk, wire, or low branch. Its diet includes a wide range of small creatures, mostly insects. Breeding takes place in the spring and, as with many Australian birds, is often communal.
Ants that harvest plant secretions also form ecological associations with insects. Several species of such ants tend riodinid and lycaenid caterpillars, and also homopterans (aphids, plant hoppers and relatives). In doing so, ants protect them against potential predators – for example, wasps. Although both riodinid and lycaenid caterpillars ...
The Australasian robin family was first introduced in 1888, as a subfamily with the spelling Petroecinae, by the English ornithologist Alfred Newton. [ 1 ] Although named after true robins , the Australian robins, along with many other insect-eating birds, were originally classified as flycatchers in a huge family Muscicapidae . [ 2 ]

A larva typically attacks the first part of the plant it encounters, namely the stem, often of a seedling, and consequently cuts it down; hence the name cutworm. Cutworms are not worms, biologically speaking, but caterpillars.

The larger American robin (Turdus migratorius) is a much larger bird named from its similar colouration to the European robin, but the two birds are not closely related, with the American robin instead belonging to the same genus as the common blackbird (T. merula), a species which occupies much of the same range as the European robin. The ...
The host plant selection is vital because it provides the food source for the young caterpillars. Females are known to have multiple broods, [ 17 ] typically up to two to three. [ 8 ] The newly hatched caterpillars will group together until they shed their skin—termed an instar for each shedding.
The pink robin (Petroica rodinogaster) is a small passerine bird native to southeastern Australia. Its natural habitats are cool temperate forests of far southeastern Australia. [ 2 ] Like many brightly coloured robins of the family Petroicidae , it is sexually dimorphic .
