Taxonomy

Avicularia juruensis was first described by Cândido Firmino de Mello-Leitão in 1923, based on specimens from Juruá in Brazil. The specific name is based on the location in which the species was found. In 1994, Gunter Schmidt separately described Avicularia urticans, based on specimens from Peru. In 2017, Caroline Fukushima and Rogério Bertani synonymized the two, saying that A. urticans was indistinguishable from A. juruensis, although there were some differences in colour.

The name A. juruensis has been misapplied to specimens of Avicularia rufa from the Brazilian states of Mato Grosso and Rondônia, south of the area in which A. jurensis is considered to occur. Apart from differences in the male and female genitalia, A. juruensis has paler leg rings, more uniformly coloured hairs (setae) on the legs, and legs I and IV more-or-less equal in length, whereas A. rufa has bright yellow leg rings, leg hairs with a whitish apex, and leg I shorter than leg IV.

Чем кормить паука-птицееда в домашних условиях

Пауки-птицееды всеядны, главное, чтобы размер предлагаемого корма был меньше тельца паука.

Молодых пауков-птицеедов кормят мелкими тараканами, мухами дрозофилами, сверчками. Также в корм можно добавлять мотыля или нарезанных мучных червей.

Взрослых пауков кормят 1-2 раза в неделю. В качестве корма для паука-птицееда подойдут живые сверчки, мраморные тараканы, саранча, мучные черви, мотыль. Некоторые заводчики кормят своих пауков новорожденными мышатами.

Корм паука-птицееда обязательно должен быть в 2 раза меньше самого паука и желательно живым

Так вы привлечете внимание птицееда к еде. Обычно пауки нападают на жертву, впрыскивая в нее свой яд и парализуя добычу таким образом

После этого птицееды разрывают жертву мощными хелицерами, впрыскивая в нее желудочный сок для того, чтобы еда переварилась. После поглощения пищи паук-птицеед может голодать неделю, а иногда и несколько месяцев. Частота кормления паука должна составлять не более 1-2 раз в неделю. Остатки пищи нужно убирать из террариума, чтобы они не начали загнивать.

Обратите внимание, что все манипуляции в террариуме домашнего паука-птицееда лучше совершать длинным пинцетом, чтобы не быть укушенным вашим питомцем

Ядовитый паук-птицеед может быть опасен для человека

Все пауки-птицееды в какой-то мере ядовиты. Хотя для взрослого человека яд птицееда не представляет смертельной опасности, он может стать фатальным для мелких животных, например, кошек. Также паук-птицеед может быть смертельно опасен для детей и людей, предрасположенных к аллергии на яд пауков.

Пауки используют яд не каждый раз, нередко наблюдаются “сухие” укусы без впрыскивания яда. При ядовитом укусе паука-птицееда возникает острая боль, повышается температура тела, не исключены судорожные и бредовые состояния.

Тело птицеедов усеяно ядовитыми волосками, которыми пауки оплетают паутину для защиты гнезда, а также счесывают с живота в случае стресса или для самозащиты.

При тактильном контакте с ядовитыми волосками, а также при их случайном вдыхании может развиться аллергическая реакция, которая выражается в сильном жжении, удушье и слабости.

Description

The adult female Avicularia juruensis has a carapace about 19 mm long and 17 wide, and an abdomen about 24 mm long and 17 mm wide. The adult male has a smaller body, with a carapace about 15 mm long and wide, and notably shorter and narrower abdomen, about 17 mm long and 12 mm wide. The fourth leg is slightly longer than the first, both being longer than the middle two. The first leg was measured as 53 mm in a female and 56 mm in a male, the fourth leg as 58 mm in a female and 60 mm in a male. The eyes are arranged in two rows of four, the front (anterior) row being slightly curved forwards and the back (posterior) row slightly curved backwards. The abdomen carries type II (setae), up to about 1 mm long in males and 0.7 mm long in females.

The mature female has two long, well separated spermathecae, expanded in the middle to about 1.5 times the width of the end portions. The mature male has a globous palpal bulb with a small subtegulum and a well developed protrusion on the tegulum. The embolus forming the tip of the palpal bulb is about 5 mm long. The forward facing side (prolateral) of the first leg has an unbranched protrusion (apophysis) on the tibia.

As with other species of Avicularia, juveniles have distinctively different colour patterns to adults. Juveniles of A. juruensis lack any kind of metallic sheen, have black tarsi contrasting with the rest of the leg which is lighter, and also have a reddish upper surface to the abdomen with a central longitudinal black stripe and separated transverse black stripes. Adults lose the stripes on the abdomen and gain a metallic sheen. There are two colour forms or «morphotypes». Morphotype 1 has a golden and pink sheen, a whitish carapace and whitish leg rings and longer light brown hairs evenly distributed over shorter darker hairs. Males appear to lack whitish tips to the hairs on the upper surface of the abdomen. Morphotype 2 has an intense purple sheen and yellower leg rings. Females have long reddish brown hairs on the front and sides of the upper abdomen over shorter darker hairs. Males have white-tipped hairs evenly distributed on the upper abdomen. Morphotype 1 is more commonly found in Brazil, morphotype 2 in Ecuador and Peru, but this is not an absolute difference. Morphotype 2 is the form previously known as A. urticans.
