Sidnia kinbergi is a small insect found in Australia and New Zealand. It’s a widespread minor pest.
The nymphs are green with small dark spots on their backs and have striped antennae.
The adults are 4-5 mm long and have a short truncated body. They can vary in colour, ranging (dorsally) from mid-green to dark-grey to red-brown, often with dark spotting or mottling. Some specimens have a pronounced dark ‘V’ on their back pointing backwards from the shoulders. The body is bright green underneath.
Sidnia kinbergi is a polyphagous (feeding on different plants) insect attacking a variety of beans species. It is also reported in asparagus, carrots, clover, Lucerne, passionfruit and wheat.
It has a life cycle of 5 nymphal instars. The adults lay pale yellow eggs (0.9mm long) which are injected into the host tissue.
Chalicid wasps have been reported parasitising eggs in New Zealand.
