The wingspan can reach 12cm. The Privet Hawk Moth is a large, dull grey moth whose green caterpillars feed on Privet. Identification The caterpillars of the Privet Hawk Moth are green with diagonal white stripes and have a horn present on the end of their tail.
Habitat The Privet Hawk Moth lives in urban areas, forests and woodlands. Feeding and diet The caterpillars of the Privet Hawk Moth are commonly seen in Sydney feeding on privet. Other behaviours and adaptations When disturbed, male Privet Hawk Moths may make a hissing sound by rubbing together a specialised set of scales and spines at the end of the abdomen.
Striped Hawkmoth. Oleander Hawkmoth. The Privet Hawkmoth caterpillar, Sphinx ligustri grows to 85 mm in length, is bright green with white, purple edged, diagonal stripes. The mainly black tail horn and black facial collar are other features that can help with identification. Other Hawkmoth caterpillars can be seen in the British caterpillar gallery and Hawkmoth gallery.
In the British Isles the caterpillars have been recorded feeding on a wide variety of foodplants but most commonly on Wild and Garden Privet and Ash, particularly on fresh lower growth and saplings. An interesting late in the year sighting was made by Barry Ofield in October of two final instar Privet Hawkmoth caterpillars in a Snowberry hedge in his Cornish garden. Despite being in their final instar and fully developed they were only 65 mm long.
Barry reared them through and they pupated successfully before overwintering as pupae. Both moths emerged the following June and were also very small as can be seen in the photo when compared to a set specimen reared by Barry in Possibly this had been a second brood that had failed to develop properly due to falling temperatures.
Nevertheless, the two emerging Privet Hawkmoths were perfect specimens in all but size. Many thanks to Barry for his observations. Hawkmoths of the Western Palearctic — Pittaway. Caterpillars of Eastern North America — David.
L Wagner. Despite the ambivalence many people have towards moths, it is impossible to deny that many of them are hugely impressive creatures well worth a closer look. There are about different species of moths resident in Britain.
Of these about are micro-moths small ones and about are macro-moths larger varieties. Some of our most distinctive moths are the hawk moths, medium to large moths in the sphingidae family. This family includes the beautiful pink and olive elephant hawk moth , the poplar hawk moth and the privet hawk moth, Sphinx ligustri , the UK's largest resident moth with a wingspan of up to 12 centimetres nearly five inches..
Moths are very closely related to butterflies. There is no scientific distinction between moths and butterflies but a few general rules apply in most cases. Butterflies always fly by day; they are usually brightly coloured; all British butterflies have club-shaped antennae though these are not always easy to see and most hold their wings vertically behind their backs when at rest except when basking.
Moths usually fly by night though some types such as burnet, garden tiger moth and the cinnabar moths fly by day ; many are deemed to be less colourful but there are a huge number of exceptions to this rule ; their antennae are rarely clubbed but do come in a wonderful range of shapes and sizes and they tend to hold their wings either flat or in a roof shape over their bodies.
The life cycle of a moth is similar to that of a butterfly. In general the caterpillar, more often called a larva when referring to moths, emerges from an egg and feeds on the leaves of its host plant. It grows by shedding its skin, a process which it may undertake about four times before being large enough to pupate. The process of pupation begins when the larva hides itself in leaf litter, underground or in a specially-made cocoon.
The skin of the larva hardens and inside the pupa the adult moth slowly develops. Eventually the moth emerges and dispersal can take place.
