|Syromastus rhombeus Rhombic Leatherbug
The only squashbug with such a broad and distinctly diamond-shaped abdomen. Nymphs have very pointed abdominal tergites, each bearing a strong spine.
Adults emerge and mate in the spring; nymphs can be found June-August feeding on sandworts, spurreys and other plants in the Caryophyllaceae. A local species which was previously mainly confined to coastal areas between Suffolk and south Wales, but is now increasingly found inland in a variety of dry grassland habitats.
