The shamrock spider can be distinguished from other orb weaver species by the several white dots on its back. The legs of Araneus trifolium are usually brown or beige colored with several white bands around the joints. The shamrock spider creates a web to catch its prey. Small flying insects who fly into the web will get stuck in the sticky net.
Spiders' legs are made up of seven segments. Starting from the body end, these are the coxa, trochanter, femur, patella, tibia, metatarsus and tarsus. The tip of the tarsus bears claws, which vary in number and size. Spiders that spin webs typically have three claws, the middle one being small; hunting spiders typically have only two claws.
The legs may instead have a light brown banded pattern. The venter has a black band enclosed by white brackets. [citation needed] Egg cocoons, which contain several hundred eggs, are generally deposited in October and are constructed of white silk formed in a flattened sphere. Immature spiders emerge from the cocoons in spring.
Orb-weaver spiders are members of the spider family Araneidae. They are the most common group of builders of spiral wheel-shaped webs often found in gardens, fields, and forests. The English word "orb" can mean "circular", [1] hence the English name of the group. Araneids have eight similar eyes, hairy or spiny legs, and no stridulating organs.
Spiders of this genus present perhaps the most obvious case of sexual dimorphism among all of the orb-weaver family, with males being normally 1 ⁄ 3 to 1 ⁄ 4 the size of females. In A. diadematus, for example, last-molt females can reach the body size up to 1 in (2.5 cm), while most males seldom grow over 0.3 in (1 cm), both excluding leg ...
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 ]

Diagram of a spider leg and pedipalp – the pedipalp has one fewer segment. Arachnid legs differ from those of insects by the addition of two segments on either side of the tibia, the patella between the femur and the tibia, and the metatarsus (sometimes called basitarsus) between the tibia and the tarsus (sometimes called telotarsus), making a total of seven segments.
