The spider species Araneus diadematus is commonly called the European garden spider, cross orbweaver, diadem spider, orangie, cross spider, and crowned orb weaver. It is sometimes called the pumpkin spider , [ 2 ] although this name is also used for a different species, Araneus marmoreus . [ 3 ]
Phidippus audax are commonly referred to as "bold jumping spiders" or "bold jumpers". [8] The species name, audax, is a Latin adjective meaning "audacious" or "bold". [8] This name was first used to describe the species by French arachnologist Nicholas Marcellus Hentz, who described the spider as being, "very bold, often jumping on the hand which threatens it". [9]
The webs are oriented vertically and have a "signal" thread attached to the center that notifies the spider when prey has been captured. Unlike Argiope garden spiders, Araneus marmoreus hides in a silken retreat to the side of the web (at the end of the signal thread). The retreat can be made from leaves folded over and held together with silk ...
Argiope aurantia is a species of spider, commonly known as the yellow garden spider, [2] [3] black and yellow garden spider, [4] golden garden spider, [5] writing spider, zigzag spider, zipper spider, black and yellow argiope, corn spider, Steeler spider, or McKinley spider. [6] The species was first described by Hippolyte Lucas in 1833.
The back row is procurved, with the two middle eyes (posterior median eyes) further in the back than the two at the sides (posterior lateral eyes). [22] The legs in females are predominantly dirty yellow to orange in colour. [10] [17] Black tips are present on the last three segments of the legs (the tibiae, metatarsi, and tarsi).
The spider seldom initiates hunting behavior to still prey, and interrupts ongoing hunting behavior when the prey ceases to move. When pursuing a prey, it at first moves rapidly, slowing down as it comes near the prey. Within 5 centimetres (2.0 in) of the prey, it presses its body close to the ground and draws the legs in toward the body.
The eggsac consists of fluffy yellow threads in a rolled leaf over a lenticular or spherical egg mass 5–12 mm (0.20–0.47 in) in diameter, which may contain up to 1,000 eggs. Juveniles are frequently preyed upon by mud daubers. [6] This species will bite if provoked, but its venom is not dangerous to humans. [7]
The adult female triangulate cobweb spider is 3 to 6 mm long (1/8 to 1/4 inch), with a brownish-orange cephalothorax and spindly, yellowish legs, and tiny hairs. The round, bulbous abdomen is creamy in color, with parallel purply-brown zigzag lines running front to back. This distinctive pattern sets it apart from other theridiids in its area.
