Jinsi ya kumtambua

Mainly dark-brown body, in earthy tones of brown and muddy-red or yellow.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

Mara nyingi huchanganywa na: 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

Akiuma

Osha jeraha na uweke barafu kupunguza maumivu. Tafuta msaada wa kitabibu kama maumivu ni makali, yanasambaa au mtu anajisikia vibaya.

Daima piga namba ya dharura kwanza (112, 000, 911). Huu ni mwongozo wa jumla wa huduma ya kwanza, si ushauri wa kitabibu. Misingi ya huduma ya kwanza

Kaa salama

Kamwe usimguse, kumkamata wala kumchokoza mnyama wa porini, hata akiwa mdogo, na hata akionekana amelala au amekufa.
Mpe nafasi. Ukikutana naye, tulia, rudi nyuma polepole na umwache aende zake.
Akikuuma: tulia, usitikisike, piga namba yako ya dharura (112, 000, 911) au nenda hospitali haraka. Kumbuka alivyoonekana, picha husaidia.

Hakuwindi wewe. Hutumia sumu yake kukamata chakula au kujilinda, na hupendelea zaidi kujificha. Zaidi kuhusu kukaa salama

Ukweli

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
