Lakas ng kamandag

Mga kagat

Lumalabas ang kamandag sa pangil o ngipin nito kapag nangangagat ito.

Ano ang epekto ng kamandag nito?

The bug injects enzymes into its prey that paralyse it and dissolve its insides. Its bite is not considered highly venomous. In people, the bite causes a wound that is very painful and lingering, with the area becoming hot and irritated, and numbness that can last for days.1

Gaano ito kapanganib sa tao?

Panganib sa tao: MasakitTalagang masakit, pero halos hindi kailanman malala.

The bite is not considered highly venomous, so it is not serious in the short term. Discomfort may last for two weeks, and in some cases up to six months. Longer-lasting problems are often linked to allergic reactions or repeated infections of the wound.1

Ano ang ginagawa nito kapag natatakot?

When threatened, it relies on camouflage, its bite, or unpleasant odours from two scent glands in its abdomen.1

Mag-ingat

Huwag kailanman hawakan, hulihin o asarin ang ligaw na hayop, kahit maliit, at kahit mukha itong tulog o patay.
Bigyan ito ng espasyo. Kung makasalubong ka ng isa, manatiling kalmado, dahan-dahang umatras at hayaan itong umalis.
Kung kagatin ka ng isa: manatiling kalmado, huwag gumalaw, tawagan ang numero pang-emergency (112, 000, 911) o pumunta agad sa ospital. Tandaan ang itsura nito, makakatulong ang litrato.

Hindi ka nito hinahabol. Ginagamit nito ang kamandag para manghuli ng pagkain o ipagtanggol ang sarili, at mas gusto pa nitong magtago. Higit pa tungkol sa pag-iingat

Mga fact

It is cannibalistic. Nymphs may prey on each other, and a female may feed on the male after mating.1

It can make a sound by rubbing the tip of its beak in a groove under its thorax. The purpose is unknown, but it may be a way of communicating.1

Nymphs are predators as soon as they hatch, but the wheel only appears after the final moult into adulthood.1

It can prey on useful insects such as lady beetles and honey bees, as well as pests.1

It is one of the largest true bugs in North America.1

In a laboratory test, parasitic wasps attacked 10 of 12 egg clusters, stopping many eggs from hatching normally.1
