Long-jawed orb weavers

Leucauge blanda

Long confused with several nearly identical relatives, this orb weaver can be told apart from them only by tiny tubercles on the male's abdomen.

WhereGrasslands and fields across East Asia
SizeFemale 6 to 10 mm, male 9 to 13 mm body length
WhenJanuary to December

The female has a brownish yellow cephalothorax edged with narrow black margins, and a silvery yellowish white abdomen marked with two brown spots near the base and three brown stripes running back toward the spinnerets.

It favors open grassland and fields rather than forest, where males build a web tilted at an angle among grass stems; across East Asia adults are most often seen from summer into autumn.
