The bold jumping spider is a small spider that hunts by sight, leaping onto its prey instead of catching it in a web. It is common across North America and is often found near people, in gardens, fields and on fence posts. It matters because it eats many crop pests.1

यसले के खान्छ?

Bold jumpers are solitary hunters that stalk live prey using their eyesight. They approach until they are within jumping distance, then pounce and grab the prey with their front legs. They prey on caterpillars, dragonflies, grasshoppers and other spiders. They do not build webs to catch food.1

यसलाई कसरी चिन्ने

A large, usually triangular white spot in the centre of the abdomen, with two smaller spots below it.1
Iridescent green chelicerae (the front mouthparts).1
White banding with fringes on the legs and pedipalps, which is more prominent in males.1
Males have more striking markings than females and tufts of hair over their eyes.1
Large forward-facing eyes, as with all jumping spiders.1

प्रायः यससँग झुक्किइन्छ: Phidippus regius has a similar abdominal pattern and lives in the same area of the southeastern United States. In the bold jumper the pale spots near the rear are more linear, while in P. regius they are more oval. The bold jumper also has pairs of matte black patches on its abdomen, which P. regius lacks.1

विष शक्ति

टोकाइ

टोक्दा यसको विषदन्त वा दाँतबाट विष निस्कन्छ।

टोक्दा वा डस्दा यसको विषले के गर्छ?

Bold jumpers use venom to immobilise their prey after biting it with their fangs.1

यो मानिसका लागि कति खतरनाक छ?

Bites from this spider are rare. A bite may happen if the spider feels threatened or is mishandled. If it is handled, it generally does not bite.1

डराउँदा यसले के गर्छ?

When threatened, they flee by jumping down and away or by hiding in small crevices.1

यसले टोक्यो भने

टोकेको ठाउँ धोऊ र दुखाइका लागि आइस प्याक राख। धेरै दुख्यो, दुखाइ फैलियो वा व्यक्तिलाई अस्वस्थ महसुस भयो भने चिकित्सकीय मद्दत लेऊ।

सधैँ पहिले आफ्नो आपतकालीन नम्बरमा फोन गर (112, 000, 911)। यो सामान्य प्राथमिक उपचार मार्गदर्शन हो, चिकित्सकीय सल्लाह होइन। प्राथमिक उपचारका आधारभूत कुरा

सुरक्षित रहू

जंगली जनावरलाई कहिल्यै नछोऊ, नसमात वा नजिस्काऊ, सानो भए पनि, र सुतेको वा मरेको जस्तो देखिए पनि।
यसलाई ठाउँ देऊ। कुनै भेट्यौ भने शान्त रहू, बिस्तारै पछाडि हट र त्यसलाई आफ्नै बाटो जान देऊ।
कुनैले तिमीलाई टोक्यो भने: शान्त रहू, नचलीकन बस, आफ्नो आपतकालीन नम्बरमा (112, 000, 911) फोन गर वा छिटो अस्पताल पुग। त्यो कस्तो देखिन्थ्यो सम्झ, फोटोले मद्दत गर्छ।

तथ्यहरू

Bold jumpers have some of the best eyesight of any spider. Their vision is widely regarded as the best among all spiders.1

Their four pairs of eyes give them nearly 360° of visual coverage around the head.1

Bold jumpers sometimes invade the webs of other spiders to steal insects that have been caught, or to attack the spiders themselves.1

Bold jumpers can change their behaviour after watching other spiders, which is rare among spiders.1

Females choose mates by watching the male's leg and body movements during his courtship dance.1

Spiderlings often spread to new places by ballooning, a way of travelling on silk threads in the wind.1

भ्रम तोड्ने

भ्रम: Like most spiders, jumping spiders catch their prey in webs.

सत्य: Bold jumpers do not build webs to catch prey. They hunt actively by sight and leap onto their victims.1
