Hoe om dit te herken

Mainly dark-brown body, in earthy tones of brown and muddy-red or yellow.1
A lighter arrow-shaped marking on the front part of the body (the sternum), with three light spots on each side.1
A lighter middle line on the abdomen, with six light spots on each side.1
Conspicuously hairy legs, palps and abdomen.1
Females reach up to 18.5 mm in body length. Males are slightly smaller, at around 12 to 15 mm. Males have larger palps and a slimmer abdomen than females.1

Word dikwels verwar met: The giant house spider has the same colouring as the domestic house spider, Tegenaria domestica. The two closest relatives, E. duellica and E. saeva, look the same as E. atrica. The three species can only be separated by microscopic measurements of the body parts.1

Gifkrag

Byte

Gif kom deur sy giftande of tande uit wanneer dit byt.

Hoe gevaarlik is dit vir mense?

Gevaar vir mense: LigSoos 'n bysteek of minder. Basies onskadelik vir mense.

Bites are not considered dangerous to humans or pets.1

As dit byt

Was die byt en sit 'n yspak daarop vir die pyn. Kry mediese hulp as die pyn erg is, versprei of die persoon sleg voel.

Bel altyd eers jou noodnommer (112, 000, 911). Dit is algemene noodhulpraad, nie mediese advies nie. Noodhulp-basiese beginsels

Bly veilig

Moet nooit aan 'n wilde dier raak, dit vang of terg nie, selfs nie 'n kleintjie nie, en selfs nie as dit lyk of dit slaap of dood is nie.
Gee dit spasie. As jy een raakloop, bly kalm, stap stadig terug en laat dit sy eie pad gaan.
As een jou byt: bly kalm, bly stil, bel jou noodnommer (112, 000, 911) of kom vinnig by 'n hospitaal uit. Onthou hoe dit gelyk het, 'n foto help.

Dit is nie uit om jou te kry nie. Dit gebruik sy gif om kos te vang of om homself te beskerm, en kruip baie eerder weg. Meer oor veilig bly

Feite

The eyes are all the same size and sit in two rows. They contain few visual cells, so the spider can probably only tell light from dark.1

Until 2018, the giant house spider was treated as one species. Research then showed three separate species, which can only be told apart under a microscope.1

Males wander while searching for females during mating season, which runs from late summer into autumn. This is when they are most often noticed.1

Males have no Y chromosome. Males carry X1 and X2, and females carry two pairs of X chromosomes. This form of sex determination is the most common in spiders and is probably the ancestral form.1
