Carabidae
More than 350 spp. 2-30mm. Antennae 11 segmented, filiform, inserted laterally between eyes and mandibles, variously setose and pubescent. Tarsi 5-5-5, usually simple although male often with protarsi dilated basally (but see Demetrias.) Head, thorax and elytra usually with discrete sensory setae. Hind trochanters are always large and project backwards behind the femurs, a character easily seen even with a card mounted specimen.     A careful count of tarsal segments will eliminate most species likely to be confused with Carabids. Omaliine Staphylinids, where the elytra almost cover the abdomen and may do so completely in carded specimens, possess distinct ocelli.     Pterostichus madidus (Fab.), very likely to be encountered almost immediately by anybody embarking upon a study of Coleoptera, is as typical a Carabid as any. Some idea of the range of variation is given below but there also specialised forms e.g. Omophron, Cicindela and Calosoma.     Found in most situations; arable land and pasture, moors and heaths, many species under bark and logs in woodland and often huge numbers among waterside vegetation. At least two species, Oodes helopoides and Carabus clathratus live underwater among vegetation. Pitfall trapping is usually very productive, searching parkland pathways with a torch on warm spring and summer evenings can reveal large numbers. M.V. light on a vertical sheet and interception nets often give good results.     For an excellent discussion of Carabid biology and ecology see Forsythe, 2000
Omophroninae
Our only species, Omophron limbatum Fab. (5-6mm) is quite unlike any other carabid; a medium sized yellowish brown beetle with metallic green markings to pronotum and elytra, almost circular and with the scutellum hidden by the basal margin of the pronotum. First recorded from Rye harbour, Sussex in 1969 (Farrow, 1971), it is now a very local insect of flooded gravel pit margins around the Sussex and Kent borders, Norfolk and Suffolk.

Cicindelinae
Commonly known as Tiger beetles our five species are all of distinctive appearance; medium sized (9-18mm) metallic species with long slender legs, large eyes and long, toothed mandibles which are crossed when at rest. Unique among carabids in having the antennae inserted on the upper surface of the head within the base of the mandibles. Identified by its elongate pronotum, Cylindera germanica L. is a local coastal species of Dorset, Hampshire and the Isle of Wight. The species rarely flies. Our four species of Cicindela run fast and fly readily in pursuit of prey. Only C. campestris L. is at all widespread. Images
Brachininae
Commonly known as Bombardier beetles due to their specialised defence mechanism; they are able to direct a spray of corrosive liquid and vapour from the abdomen towards a potential threat. Although charcterised by the number of visible abdominal sternites, seven in the female and eight in the male as opposed to six in the carabininae, they are readily recognised on general appearance. Brachinus crepitans (L.) (6-9mm), our only resident species, is light reddish brown but for the dark metallic blue or green elytra and has the entire upper surface finely pubescent. It is a very local insect of grassland and open wasteland throughout southern England and southern Wales. Our other species, B.sclopeta (Fab.), is a very occasional immigrant with recent records (2005) from the London area. It is smaller than crepitans with the base of the elytral suture broadly red.
