Field Notes
Description:
Harmonia axyridis is a "typical" coccinellid beetle in shape and structure, being domed and having a "smooth" transition between its elytra (wing coverings), pronotum and head. It occurs in three main color forms: red or orange with black spots (known as form succinea); black with four red spots (form spectabilis); and black with two red spots (form conspicua). However, numerous intermediate and divergent forms have also been recorded. The species is typically large (7–8 mm long) and even more dome-shaped than native European species (these characteristics distinguish H. axyridis from native species in the UK). It often has white markings (typically defining an "M"- or "W"-shaped black area) on its pronotum, and usually brown or reddish legs
Habitat:
H. axyridis is native to eastern Asia from central Siberia, Kazakhstan and Uzbekistan in the west, through Russia south to the Himalayas and east to the Pacific coast and Japan, including Korea, Mongolia, China and Taiwan. As a voracious predator, it was identified as a biocontrol agent for aphids and scale insects. Consequently, it has been introduced into greenhouses, crop fields and gardens in many countries, including the United States and parts of Europe. The species is now established in the United States, Canada, Argentina, Brazil, the United Kingdom, Denmark, the Netherlands, Belgium, Luxembourg, France, Germany, Poland and South Africa.[2]
