The leaves of various eucalyptus plants are observed to determine whether there is predation by the bronze bug present. Predation is evident due to the black larvae present on the leaves. These plants will then be noted if predation has occurred‚ this is evident due to branch dieback‚ tree mortality and the yellowing of the foliage. Scars become evident once predation occurs on the leaves‚ these scars will therefore

to a donor body. Male ticks are black. Females have a red abdomen and some black near the head. Adult ticks usually feed on deer but some times feed on humans accidentally. Deer ticks go through three life stages. The first stage is the larva. The larvae are small and tan colored. They usually feed on things like chipmunks‚ mice‚ and other small animals. Nymphs are a little bit larger than the larva. They are beige with a dark head. Nymphs usually feed on larger animals such as birds and raccoons

days. After the eggs hatch‚ the mites migrate to the skin surface and molt. The larval stage‚ which emerges from the eggs‚ has only 3 pairs of legs. This form lasts 2 to 3 days. After larvae molt‚ the resulting nymphs have 4 pairs of legs. This form molts into slightly larger nymphs before molting into an adult. Larvae and nymphs may often be found in short burrows or hair follicles. They look similar to adults‚ only smaller. Adults are round‚ sac-like eyeless mites. Females are 0.3 to 0.4 mm long
