Crucifer Shieldbug - Eurydema oleracea
Also known as - Cabbage or Brassica Bugs

A quite small shield bug species 5-7mm (0.2-0.275in) long, black head and body with a green or blue metallic sheen, occurring in two colour forms, red and white for both males ♂ and females ♀.  These forms are seen as appropriately coloured dorsal spots with the red form being rarer than the white.  Their eggs are barrel shaped and yellow green usually number about 55-80 incubated for about fifteen days, nymphs and first instars are black with succeeding instars gaining the coloured spots becoming clearer with older instars (five instars in all).  Host plants are Cruciferae (cabbages).  There are usually two generations a year during June and July and August to October with adults hibernating over winter in cracks or crevices in the soil and on trees.  A rare parasitic fly Clytiomya continua is a parasite of the Crucifer Shieldbug.  Male Crucifer Shieldbugs are larger than the female.
