Description

Adult black-headed mirids are slender with a black head and shoulders and light silvery wings. Generally mirid nymphs are difficult to identify. The nymphs of this genus are about 3mm long, pale green with rounded bodies and have black eyes. They are very similar to green mirid nymphs but are smaller and a paler green. They also look like aphids, but do not have the tubular extensions on their bodies.

Adult size: 3mm

Out and about

About in spring and summer.Bugs of this genus found in some arctic regions as well as in the tropics including China, South America, Australia and Indo-Pacific areas. Tytthus mundulus occurs throughout the Indo-Pacific region and in Australia it is found in Queensland.

Reproduction and Life cycle

Eggs are laid singly, usually into leaf tissue with just the tip of the egg protruding slightly. The female can lay up to 80 eggs in her lifetime. The cycle from egg to adult can be as quick as 3 weeks in ideal, warm conditions although numbers appear to reduce if it remains hot for a few days, or if there is heavy rain or storms. Eggs can remain unhatched over winter and adults can shelter in weeds till the weather warms up.
