Argiope bruennichi participate in sexual cannibalism. The females of this species, typically much larger than the males, almost always consume their male counterparts after copulation. [9] [7] To combat this, males often wait in or near an immature female's web until she completes her final moult and reaches sexual maturity.
Argiope bruennichi is commonly known as the wasp spider. In Australia , Argiope keyserlingi and Argiope aetherea are known as St Andrew's cross spiders , for their habit of resting in the web with paired legs outstretched in the shape of an X and mirroring the large white web decoration (the cross of St. Andrew [ 2 ] having the same form).
Argiope trifasciata (the banded garden spider or banded orb weaving spider) [2] is a species of spider native to North and South America, but now found around the world. [3] It can be found in certain areas of Europe, namely the Iberian Peninsula, the Canary Islands, and Madeira. [4] [2] The similar looking Argiope bruennichi is common in the ...
In the cannibalistic and polyandrous orb-web spider Argiope bruennichi, the much smaller males are attacked during their first copulation and are cannibalized in up to 80% of the cases. [23] All surviving males die after their second copulation, a pattern observed in other Argiope species. Whether a male survives his first copulation depends on ...

Argiope aurantia males can lose legs in combat, with the loss more prevalent in smaller males, evidence that larger males are favored in male-to-male competition. [2] In the water spider Argyroneta aquatica, where males and females permanently live in the water [10] the males are larger, indicating sexual selective pressures for large body size ...
Spider silk structure: crystalline beta-sheets separated by amorphous linkages. Silks have a hierarchical structure. The primary structure is the amino acid sequence of its proteins (), mainly consisting of highly repetitive glycine and alanine blocks, [4] [5] which is why silks are often referred to as a block co-polymer.
