Wheel bug
The wheel bug is a large assassin bug with a wheel-shaped crest on its back. It is the only wheel bug found in the United States, and it hunts caterpillars and beetles. Gardeners value it because it helps keep pests down.1

Kako ga prepoznati
- Adults are grey to brownish grey, and black shortly after moulting.1
- Adults have a wheel-shaped or cog-shaped ridge on the back of the thorax. Young nymphs do not have this wheel yet.1
- Nymphs have a bright red or orange abdomen.1
- Adults can grow up to 38 mm long. Females are somewhat larger than males.1
- They move and fly slowly, and make a noisy buzzing sound in flight.1
Otrovna snaga
Otrov izlazi kroz očnjake ili zube kad ugrize.
Što radi njegov otrov kad ugrize ili ubode?
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
Koliko je opasno za ljude?
Opasnost za ljude: BolnoMože jako boljeti, ali gotovo nikad nije ozbiljno.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
Što radi kad se uplaši?
When threatened, it relies on camouflage, its bite, or unpleasant odours from two scent glands in its abdomen.1
Ako ugrize
- Kod dlačica gusjenica koje peku: skini ih ljepljivom trakom, a zatim operi kožu. Ne trljaj.
- Kod ugriza: operi i ohladi. Potraži liječničku pomoć ako se osoba osjeća loše ili lako krvari.
Uvijek prvo nazovi broj za hitne slučajeve (112, 000, 911). Ovo su opće upute za prvu pomoć, a ne liječnički savjet. Osnove prve pomoći
Ostani na sigurnom
- Nikad ne diraj, ne hvataj i ne zadirkuj divlju životinju, čak ni malu, i čak ni ako izgleda kao da spava ili je mrtva.
- Ostavi joj prostora. Ako je sretneš, ne paniči, polako se odmakni i pusti je da ode svojim putem.
- Ako te neka ugrize: ne paniči, miruj, nazovi broj za hitne slučajeve (112, 000, 911) ili brzo idi u bolnicu. Zapamti kako je izgledala, fotografija pomaže.
Ne želi ti ništa loše. Otrov koristi za lov hrane ili za obranu i mnogo bi se radije sakrilo. Više o sigurnosti

Činjenice
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
