Both of these species possess white or light-brown-colored hairs with orange tufts behind their heads, making them easy to spot. The Sycamore tussock caterpillar looks identical to the banded tussock caterpillar species, ( Halysidota tessellaris), but the latter species’ habitat is mostly limited to forested areas where they do not pose a threat to residents. They also exhibit one pair of white hair-pencils near the back of their body.
They exhibit two pairs of long, orange hair-pencils and two pairs of white hair-pencils towards the front of their body. The Sycamore Tussock caterpillars have yellow-orange heads and bodies covered with hair, and they can grow to approximately 25–35 mm in length. Sycamore Tussock Caterpillar (Halysidota harrisii) As with all hairy caterpillars care should be taken if handling as the hairs may cause irritation to the skin. The caterpillars are frequently found in urban and rural areas where the larval foodplant of Sycamore and London Plane trees occur. They feed on a variety of deciduous trees including sycamore and maples.They are well known for dropping out of trees and on occasions landing on walkers. The fully grown, brightly coloured, hairy caterpillars are commonly seen in late summer and early Autumn when they leave the trees to wander in search of somewhere to pupate. Sycamore moth caterpillar ( Actronicta aceris) The large yellow and black caterpillars of this moth feed in groups and can consume large areas of foliage on a wide range of shrubs and trees. They are frequently found in woodland, open countryside and urban gardens and parks. The fully grown caterpillar is up to 75mm in length and has a distinctive trellised yellow and black patterning with a covering of fine pale hairs.Their black and yellow colouration serves to warn predators that they are distasteful, and their hairs cause irritation to anything trying to swallow them. Woollybear eats most of the plants grown in the garden as well as many species of ground cover found many landscape.Īlso Read: Different Types of Striped Caterpillars Buff-Tip Moth Caterpillar The caterpillars occur in the fall and overwinter as pupae in cocoons attached to leaves. The adults have a few small dark spots on their white wings and white and orange abdomens. The caterpillars of yellow woolly bear moths are seen more often than the adults, which fly during the night. Yellow Caterpillars Yellow Woolly Bear CaterpillarĬaterpillars of yellow woollybear are densely hairy and pale colored ranging from light brown to yellow to nearly white uniformly dispersed over the entire body. The head is not separately colored nor are there any tufts of different colors. Giant Peacock Moth Caterpillar ( Saturnia pyri).Tasar Silkworm Caterpillar (Antheraea mylitta).American Dagger Caterpillar ( Acronicta americana).Sycamore Tussock Caterpillar ( Halysidota harrisii).Yellow Woolly Bear ( Spilosoma virginica).Here are some of the yellow species of caterpillars that are frequently found in woodland, open countryside and urban gardens and parks: Many of these caterpillars are most obvious when they’re fully grown and looking for a place to either pupate or settle down for the winter, though some are easily spotted on their favourite food plants. Young caterpillars are often found in groups, spreading out over the plant as they grow larger. This causes a window effect where the epidermis of the upper leaf surface remains undamaged. Very small caterpillars are not able to chew and therefore graze the underside of leaves. Most species feed on leaves and young shoots, and their enormous feeding capacity can rapidly decimate a plant. Butterflies and moths form the order Lepidoptera, a very large group with more than 150,000 species, that are easily distinguishable from other insects.Caterpillars can cause serious economic damage. Caterpillars are the larvae of butterflies and moths.
