Growing citrus in my area is quite a challenge with lots of insect pests let alone avian ones like cockatoos.Numerous fruit piercing moth species attack my mandarins and oranges before they ripen. The foliage of trees is consumed by several species of large phasmids, whopping Valanga irregularis grasshoppers and even emperor moths. The following black and white (with bits of red and blue) swallowtail butterflies have their caterpillars on citrus in my district.
Dainty swallowtail, Papilio anactus (WS Macleay, 1826)
Orchard swallowtail, Papilio aegeus (Donovan, 1805)
Ambrax swallowtail, Papilio ambrax (Boisduval, 1832)
Fuscus swallowtail, Papilio fuscus (Goeze, 1779)
Chequered swallowtail, Papilio demoleus (Linnaeus, 1758)
The smaller aphids,and sucking bugs also give me grief at times but fruit flies and leaf miners are leaving the fruit and trees alone. Pinks disease is a constant fungal issue but we are talking insects now. Maybe may area and location are prone to insects pests and I do like butterflies. Are other people finding their citrus trees and fruit on the menu of insects a little too much?
