Hedychridium roseum – Cavenham Heath NR

Habitat
Found in open sandy areas associated with the nesting habitat of its host (see below). Present on inland sandy areas including lowland heaths, and coastal sandy areas.
Flight period
Probably univoltine; July and August.
Flowers visited
Wild carrot (Daucus carota), sheep’s-bit (Jasione montana) and yarrow (Achillea millefolium).

Parasitic biology
The hosts of this species are the Crabronid wasps Astata boops (see Map 083), Tachysphex pompiliformis (see Map 087) and Dienoplus tumidus (Morgan, 1984, as Gorytes tumidus). However, the distribution of A. boops and H. roseum are so similar in England that A. boops would seem to be the main, or even the only, host. For further information see H. ardens.

Green tiger beetles (Cicindela campestris) Cavenham Heath

Green tiger beetles (Cicindela campestris) are ground beetles, easily recognised by their iridescent green colouring and the yellowish spots on their back. There are over 40,000 species of ground beetle worldwide and Britain has over 350 species.
Adult Green tiger beetles can be seen from April to September and are between 10.5-14.5mm in length. They have long legs that make them agile when hunting for prey and large eyes making them the perfect predator. If disturbed, they will fly short distances making a buzzing sound in flight.
Green tiger beetles have strong sickle shaped jaws (mandibles) that have several teeth. Adults feed on any small invertebrates they can catch including spiders, caterpillars and ants.
Green tiger beetles breed in the summer and their eggs are laid separately in small burrows in the ground. When the egg hatches the larvae remain in the burrow feeding and growing.
