Hula nini?

It eats a wide range of insects, including crickets, fly grubs, cockroaches, mealworms and beetles, and sometimes smaller spiders. It waits for prey and hunts alone, mostly at night. Females wait in their burrows, while males roam and look for prey.1

Jinsi ya kumtambua

The carapace (the hard upper shell of the front body) is brown, with a distinct yellow stripe running from the front eyes down the body.1
The underside of the abdomen has distinct black spots.1
It is around 17 mm long on average, which makes it one of the smaller wolf spiders.1
Males have yellow legs without distinct markings. Females have reddish brown legs without markings or bands.1
It does not make webs and is usually active at night.1

Mara nyingi huchanganywa na: It is often mistaken for the nursery web spider (Pisaurina mira). The wetland giant wolf spider has a brown carapace with a distinct yellow stripe from the front eyes, and black spots on the underside of the abdomen. It is also similar to T. georgicola, but it has black spots that T. georgicola lacks, and its faint yellow stripes do not extend as far.1

Nguvu ya sumu

Kuumwa

Sumu hutoka kupitia meno yake ya sumu au meno anapouma.

Sumu yake hufanya nini?

Its bite injects venom. In people, the venom causes only minor pain and swelling.1

Ana hatari gani kwa watu?

Hatari kwa watu: HafifuKama kudungwa na nyuki au chini ya hapo. Kimsingi hana madhara kwa watu.

It is not very aggressive and will not attack people unless provoked. Its bite is not medically significant to humans, and antivenom is rarely needed.1

Habari njema: madaktari wana dawa (ya kuzuia sumu) au matibabu ya hili.1

Hufanya nini akiogopa?

It hides in burrows, under stones or boards, and relies on camouflage and speed to avoid predators. If needed, it will bite a predator and inject venom.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

Females can cannibalise males during or after mating. Smaller males are more likely to be eaten, and hungry females are more likely to do it.1

This species does not build webs. Females make silk-lined burrows under stones or boards instead.1

Males live for just over a year, while females often live for around two years.1

Hunger affects behaviour. Well-fed females made significantly more burrows than starved ones in a 1999 study.1

Females are much larger than males. Mature females weigh more than 300 mg and have carapaces about 6.5 mm wide, while males usually weigh more than 200 mg and have carapaces about 4.5 mm wide.1

Kuvunja dhana potofu

Dhana potofu: Wolf spider bites are dangerous and medically serious.

Ukweli: The bite injects venom, but it usually causes only minor pain and swelling. The spider is not very aggressive and will only bite when provoked.1
