The Top 5 Largest Jumping Spiders

Jumping spiders comprise the largest percentage of the spider population with more than 6000 species (that we know about). They can live comfortably in various habitats worldwide, except on the south and north poles. Furthermore, you can distinguish the species from their sizes as members of each species have a specific size range.

Below are the top five largest jumping spiders:

  • The Giant Jumping Spider (Hyllus giganteus)
  • Heavy Jumping Spider (Hyllus Diardi)
  • Regal Jumping Spider (Phidippus regius)
  • Bold Jumping Spider (Phidippus audax)
  • The Emerald Jumping Spider (Paraphidippus aurantius)

1. The Giant Jumping Spider (Hyllus giganteus)

The giant jumping spider is the largest species in the family. Carl Ludwing Koch, a German scientist, discovered the first giant jumper in 1846. They are native to Australia and Samatra where they dwell mostly on trees in thick forests.

You can tell a giant jumper from other species with its bright colors including blue, green, and red. They also have a remarkable eyesight that enable them to differentiate colors.

They are common in woodlands and dense fields, but sometimes you may spot them crawling on your walls. Moreover, they leave a trail line behind them so that they do not fall whenever they miss a jump.

The male regal jumper can be smaller than the female, about 6 to 18 mm and 7 to 22 mm respectively. Nonetheless, this is not a constant rule. Again, you can easily tell the two apart since the male has unique features such as blue or green fangs combined with white or black colors.

Bold jumpers are day-hunters and prefer to move alone. Therefore, the sharp vision is the biggest advantage they have since they use it to observe predator and prey. Additionally, they also use visual communication in reproduction where the males lift their legs as a signal to attract the females.

Furthermore, their bodies are hairy and the female is larger than the male; 8 to 15 mm long and 6 to 13 mm long respectively.
