large flies with females reaching 45-50 mm across. They have long, spindly legs and one pair of narrow, clear wings with clearly visible veins. Eggs are
abdomen paler; females are 1.4-1.7 mm long and males are 1.1-1.2 mm long. The legs are entirely white or yellow. The greenhouse thrips is parthenogenic, it
has a single pair of wings. First-instar nymphs are 0.3 mm long and have legs, but soon settle to form circular, initially white scales. Circular scales
cornicles (or siphunculi) are short and usually darker than the body. The legs are light yellow with darker tips. Adult wingless aphids are 1.5-3.1 mm long
while the wingless forms (apterae) are yellow with black cornicles, antennae, legs, and cauda (tip of abdomen). Nymphs are similar to apterae in appearance
mouthparts, and the rest of the body. All mobile stages have only two pairs of legs, whereas other mite groups have four pairs. Eggs are roughly 0.05 mm in diameter
a number of darker bands, and their length exceeds that of the body. The legs are also long, there are two distinctive dark green spots on the abdomen
mm long), red-brown body colour and covering of granular, white wax. The legs, antennae and body hairs are conspicuously black. The nymphs and adult females
lie in a characteristic 'C-shaped' position. They possess three pairs of legs, of which the middle and hind pairs are approximately the same length. Pupation
adult potato aphid is a large, slender aphid with long, green cornicles, long legs, and a long cauda. Adults are usually green, but may also be pink or red
