Bigeyed bug
Identification tip: Bigeyed bug adults and nymphs are oval,
somewhat flattened, about 1/4 inch (4 mm) long, usually brownish or
yellowish, and have a wide head with prominent bulging eyes. Bigeyed
bugs can be confused with other hemipterans in the same family (Lygaeidae),
as well as insects in the Miridae family. |
Calocoris nymph
Calocoris
Identification tip: Adult Calocoris can be distinguished from lygus
bugs by the presence of two black dots on the back, just behind the head. Calocoris nymphs
do not have red-tipped antennae and black spots on the back as lygus nymphs do. Calocoris nymphs
tend to be longer and narrower than lygus nymphs and have fine black hairs on
the body |

Cotton aphid
Identification tip: Cotton aphid is highly variable in body
size and color, and adults may be winged or wingless. Nymphs and adults
of wingless cotton aphids vary in color from yellow to green to nearly
black. Nymphs that are developing into winged adults look very different
from the nymphs developing into wingless adults: they bear small welts
or protuberances on their bodies and may be covered with a coat of
dusty-like whitish wax. Their body color is often greenish blue, or
amber and blue. |
