Body color chestnut to reddish black with amber-colored legs and paranota. Mid-body paranota are rather blunt and rounded (not extending past posterior segment margin), but increase in length and sharpness towards the tail. A transverse groove is present on each body segment, a trait shared with other Paradoxosomatids. (2)
Range
Native to Asia, introduced to North America and found throughout the lower 48 states and southern Canada
Life Cycle
Lays clutches of 40-150 eggs in all months of the year, reaches maturity in 5 to 6 months. (2)
See Also
Asiomorpha coarctata, which has sharper paranota (midbody keels projecting behind segment margin), a somewhat darker body color, and longer gonopods- reaching 5th segment legs (vs short to 6th segment legs in O. gracilis).
