Moč strupa

Ugrizi

Strup pride ven skozi strupnike ali zobe, ko ugrizne.

Kaj naredi njen strup, ko ugrizne ali piči?

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

Kako nevarna je za ljudi?

Nevarnost za ljudi: BolečeLahko zelo boli, a skoraj nikoli ni resno.

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

Kaj naredi, ko se prestraši?

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

Če ugrizne

Pri ožigalnih dlačicah gosenic: odstrani jih z lepilnim trakom, nato umij kožo. Ne drgni.
Pri ugrizih: umij in ohladi. Poišči zdravniško pomoč, če se poškodovanec slabo počuti ali hitro krvavi.

Vedno najprej pokliči številko za klic v sili (112, 000, 911). To so splošna navodila za prvo pomoč, ne zdravniški nasvet. Osnove prve pomoči

Ostani varen

Nikoli se ne dotikaj divje živali, je ne lovi in je ne draži, tudi če je majhna in tudi če je videti, kot da spi ali je mrtva.
Pusti ji prostor. Če jo srečaš, ostani miren, počasi stopi nazaj in jo pusti, da gre svojo pot.
Če te ugrizne: ostani miren, ne premikaj se, pokliči številko za klic v sili (112, 000, 911) ali hitro pojdi v bolnišnico. Zapomni si, kako je izgledala, fotografija pomaga.

Ne preži nate. Strup uporablja, da ulovi hrano ali se zaščiti, in se veliko raje skrije. Več o varnosti

Dejstva

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
