Giant shield bug

Giant shield bug

Pycanum alternatum

A species of Pycanum

Adorned with a distinctive shield-like structure on its back, giant shield bug is known for its vibrant coloration which may act as a warning to potential predators. During its developmental stages, it undergoes incomplete metamorphosis, with its younger phase resembling smaller versions of adults and feeding on the same host plants. Its presence is a clear indicator of the health of its habitat, as it thrives in environments with ample plant diversity to sustain its herbivorous diet.

Life Cycle of Giant shield bug
Egg The eggs of giant shield bug are typically laid in clusters and are oval-shaped. Initially, they are bright and gradually darken as development proceeds. They vary in size depending on the species but are generally tiny and immobile.
Nymph Upon hatching, the giant shield bug nymphs resemble miniature adults but lack fully developed wings and reproductive structures. As they molt, they grow progressively larger, develop wing pads, and change color. They are active feeders and progressively gain adult-like features.
Adult Emerging from the final molt, the adult giant shield bug sports fully formed wings and functional reproductive organs. Its body is harder and more distinctly colored than in the nymph stages. Adults are mobile, focusing on mating, and if female, laying eggs.

Are Giant shield bug harmful to humans?

The insect abdomen of the Lycidae has odorous glands, and after sexual maturity, the odorous glands also mature. When they are frightened, they will eject odorous liquid from the odorous glands and wait for the opportunity to escape. This liquid is irritating and corrosive, and has a repellent effect on some insects. For most people, insects of the Lycidae family only leave a nasty smell.
A few people's skin will have an allergic reaction to odorous fluid, which is red and swollen with a burning sensation.
If this smelly liquid enters the eyes accidentally, it will cause different degrees of photophobia, tearing pain, and visual impairment. If it is not handled in time, it may cause more serious damage to the eyes, such as corneal ulcers and bulbar conjunctival erosion.

Hurt Plant

When giant shield bug feeds on plants, it primarily targets leaves and fruits, extracting vital fluids through piercing and sucking actions. This causes the host plant to exhibit signs of stress, which might include wilting, discoloration, and eventually a decrease in overall vitality. The damage can lead to reduced photosynthesis and impaired growth, negatively impacting the plant's health and productivity.
