Two species of garden spiders are found in Quebec: Argiope aurantia Lucas (the yellow garden spider) and Argiope trifasciata (the banded garden spider)
These large, brightly coloured spiders, which are often found immobile in the centre of their large web marked with a zigzag, are among the most beautiful and easiest spiders to recognize.
The yellow garden spider’s abdomen is black and yellow and pointed at one end. Sometimes its abdomen also features white, orange and red patches. Its legs are black and may have coloured stripes. Females are much larger than males. They measure between 19 and 28 mm long, while their partners are only 5 to 8 mm long.
The banded garden spider’s pale yellow abdomen has horizontal silver, yellow and black spots. This species is a bit smaller. Females measure between 15 to 25 mm long, while their partners are only 4 to 5.5 mm long.
