怎麼認出牠

Adult males are black with several white markings on the back of the abdomen. Their first pair of legs has an alternating black and white fringe.1
Adult males have large, iridescent green-blue-violet jaws (chelicerae) with a small bump (tubercle) on each.1
Adult females are covered mostly in brown, orange, tan or grey scales, and may have white or orange markings on the abdomen.1
Adult females have tufts of hairs (setae) around the eyes, which males lack.1
Juveniles are pale brown with reddish-brown markings on the abdomen rimmed with black, and have dark red fangs.1

毒液力量

咬

咬的時候，毒液會從毒牙或牙齒出來。

牠的毒液有什麼作用？

Documented bites have caused severe pain, similar to a bee sting, with swelling that can last up to three months. This reaction is likely due to individual sensitivity or local inflammation.1

牠對人有多危險？

對人的危險: 輕微跟蜜蜂螫差不多或更輕微。對人基本上無害。

The regal jumper is considered minimally harmful to humans. Rare documented cases have involved severe pain and long-lasting swelling after a bite, which may depend on the individual person.1

如果牠咬人

清洗咬傷處，用冰敷袋冰敷止痛。如果很痛、疼痛擴散或傷者覺得不舒服，要就醫。

一定要先打緊急電話（112、000、911）。這是一般急救指引，不是醫療建議。急救基本知識

注意安全

絕對不要碰、抓或捉弄野生動物，就算是很小的動物，就算牠看起來在睡覺或已經死了也一樣。
給牠空間。如果遇到了，保持冷靜，慢慢往後退，讓牠自己離開。
如果被牠咬了：保持冷靜，保持不動，打緊急電話（112、000、911）或趕快去醫院。記住牠的樣子，有照片會很有幫助。

牠不是想來抓你。牠用毒液來捕捉食物或保護自己，而且牠更想躲起來。更多安全知識

小知識

This is the largest jumping spider in eastern North America.1

A 2017 web series, Lucas the Spider, helped increase the popularity of this species as a pet.1

In large males, the first pair of legs is disproportionately bigger than in smaller males.1

In 2026, Build-A-Bear Workshop created a jumping spider plush, reflecting the species' growing popularity as a pet.1

In southern populations, juvenile females may develop scales as early as the third instar, while males stay black and white for their whole life.1
