Paraplectana tsushimensis

Paraplectana tsushimensis is a spider in the orb-weaver family, Araneidae, native to China, Japan, and Taiwan. It is commonly called the ladybird mimic spider.

The species belongs to the genus Paraplectana. The scientific name of the species was first published in 1960 by Yamaguchi.

The ladybird mimic spider has evolved to mimic the appearance of the ladybird. These spiders have bright red or orange bodies with black spots. Their body shape also mimics the ladybird, round. To take its mimicry even further, the ladybird mimic spider will move its legs in the same way that a ladybird does.

The size of the ladybird mimic spider can vary. Their sizes can range from a few millimeters to about one centimeter. They use their size to their advantage, easily moving through foliage and hide.

This spider is known for its patient hunting style. Rather than make webs, the ladybug mimic spider will wait on leaves, flowers, or tree bark to wait for its prey to come into its striking range.

Despite its skill for hunting, the ladybird spider will eat nectar as well as insects. This strategy helps to ensure its survival and provides them with more necessary nutrients for reproduction.

The male ladybird mimic spider has an intricate courtship ritual it uses to attract females during mating season. It will use specific movements and vibrations, a dance of sorts. The female will choose a partner based on the performances.

Like most spiders, the female ladybird mimic spider will lay its eggs inside of a silk egg sac. Until the eggs hatch, the mother spider will wrap herself around the sac, safeguarding it.

The ladybird mimic spider is a primarily solitary species. They will establish their territory, defending it from other spiders, primarily male spiders, who can pose a threat during the mating season.
