Heteropteran bugs are members of the true bug order. This means that they do not possess jaws like most other forms of insects, but have a tube like rostrum for sucking the liquids from plants or animals.The well known cicadas, leaf hoppers, aphids and shield bugs are prime examples. The photo below shows a Picromerus bidens shield bug resting on a leaf tent made by a Dolomedes spider.
The bug below is a specimen of Corizus hyoscyami, a rather rare species to be found in dry sandy districts such as southern heathland.I found both bugs on a dry patch of heath by Bournemouth airport.
