Squash Bug Notice the hole in their side? Air enters the respiratory systems of insects through a series of external openings called 'spiracles'. These external openings, which act as muscular valves in some insects, lead to the internal respiratory system, a densely networked array of tubes called tracheae. This network of transverse and longitudinal tracheae equalizes pressure throughout the system. Coreus marginatus,Dock bug Click/tap to enlarge

The Dock bug

"Coreus marginatus", commonly called the dock bug, is a species of squash bug. It is a speckled brown insect with a broad abdomen, and is common in most parts of Europe. It is often found in dense vegetation, such as hedgerows and wasteland, where it mainly feeds on the leaves and seeds of docks and sorrels.
