Uma siluma

Geza inxeba lokulunywa bese ubeka iphakethe leqhwa phezu kwalo ngenxa yobuhlungu. Thola usizo lwezokwelapha uma ubuhlungu bunamandla, busabalala noma umuntu ezizwa engaphilile.

Njalo shayela kuqala inombolo yezimo eziphuthumayo (112, 000, 911). Lokhu kuyiseluleko sosizo lokuqala esijwayelekile, akusona iseluleko sezokwelapha. Izisekelo zosizo lokuqala

Hlala uphephile

Ungalokothi uthinte, ubambe noma ugcone isilwane sasendle, ngisho noma sincane, futhi ngisho noma sibukeka silele noma sifile.
Sinike isikhala. Uma uhlangana naso, hlala uzolile, uhlehle kancane bese usiyeka sihambe ngendlela yaso.
Uma sikuluma: hlala uzolile, ungashukumi, shayela inombolo yezimo eziphuthumayo (112, 000, 911) noma uye esibhedlela ngokushesha. Khumbula ukuthi besibukeka kanjani, isithombe siyasiza.

Asikuzingeli wena. Sisebenzisa ubuthi baso ukuze sibambe ukudla noma ukuzivikela, futhi singancamela ukucasha. Okwengeziwe mayelana nokuhlala uphephile

Amaqiniso

Below or inside its web, there can be many dead insects, from stink bugs to other spiders and even wasps.1

Among the Steatoda spiders, it is one of the most voracious and prey-driven, even though it is one of the smaller species.1

Because of its limited eyesight, it relies mostly on vibrations travelling through its web to find prey and to sense larger animals that could harm it.1

Its egg sac is loosely woven silk and is about the same size as the spider itself.1

It spends hours each day building its web and eats during only part of its day.1
