Leucauge is a spider genus of long-jawed orb weavers, with 174 different species (2017).
The body and leg shapes and the silver, black and yellow markings of Leucauge females make identification of the genus relatively easy.
They have two rows of long, slender curved hairs on the femurs of the fourth leg.
In most cases the web is slanted rather than vertical and the spider rests in the middle of the web with its underside facing upwards.
