Arthropods, thick rafters
Argiope macrochoera
Thick rafters, belonging to the phylum Arthropods, Arachnids, Arachnids, Garden Spiders, Golden Spiders. It inhabits high temperature and high humidity rain forests and monsoon rain forests, often weaving large circular nets between branches or shrubs, feeding on insects. It is mainly distributed in Guangdong, Hainan, Yunnan and other provinces. Photo taken in Pu'er.
Females of the thick rafters are brightly colored , with black dorsal carapace and densely covered with white hairs ; the thorax and antennae are yellow ; and the foot has an interspersed yellow and black ring. The dorsal mask of the abdomen has a number of irregularly shaped and interspersed white, yellow, black and red stripes, with nearly circular white spots in the middle and 1/3 of the end, and the ventral surface is black with 2 yellow longitudinal arcs, and the arcs are flanked by multiple white spots.
Compared with the "enchanting beauty" of female spiders, male spiders look very ordinary, their body color is dull, and the dorsal carapace is light yellowish brown or reddish brown, which can be integrated with the trunk when not moving.
In the order spiders, a large proportion of females have a "butcher" situation, thick rafters are no exception, the study found that before mating and after mating time, if the male spider does not rush to escape, 89% of them will be killed by the "wife". After all, the female spider is about 1.5 to 2 cm long, the foot extension can easily reach about 5 cm, and the male spider is less than a quarter of the female spider, so it is easy to be "KO" by the female spider.
Unlike the nomadic spiders introduced in previous issues, the thick rafters are a spider that "guards the rabbit" by weaving a web, which can weave a large circular web between branches or shrubs, and more interestingly, the web of the thick rafters has a jamnet (that is, a stinge), that is, a web composed of multiple "letters" at the red circle. The study found that such a jamming net may arouse the "curiosity" of some prey, making them willingly "self-cast nets".
