Click Beetles (Elateridae) of Nottinghamshire
 
The UK has a total of 65 species of Click Beetles and Nottinghamshire certainly has it's fair share of species.

Much of this wealth of species is due to Sherwood Forest, which is particularly notable for the number of rare beetles it holds, including several nationally rare Click Beetles. Some of these we have illustrated here and these photographs (hopefully) at least begin to fill in another gap in the county's internet resources.

Click Beetles (Elateridae) get their name from their ability to flick themselves upright should they fall onto their backs, and is frequently used as a defence mechanism when the beetle feels threatened. They are able to do this by flexing a well developed joint between the first and second thoracic sternites.

  Many Click Beetles are quite drab in appearance, but there are exceptions, of which some of the red Ampedus species are the most colourful. Unfortunately, these beetles are uncommon and they are restricted to the Sherwood Forest area of Nottinghamshire by habitat requirements. Although any of the Ampedus group can be stumbled upon quite accidentally, it usually takes some searching before any success.

From May and throughout much of the Summer months Click Beetles can be found. Athous haemorrhoidalis is the most abundant species of all and common in most grassy areas and roadside verges, but some of the smaller species can be equally as common, but more difficult to find due to their small size.

Correct identification of many species can be difficult and we have taken great care to ensure that all species shown here are correct, but Click Beetles do make an interesting study for any naturalist wishing to broaden their interests.

Nottinghamshire (VC56) Elateridae

The following list of Elateridae are known from the county. There are a couple of historic records listed in Appendix A of the "List of species of conservation concern in Nottinghamshire of the Nottinghamshire Local Biodiversity Action Plan", (of Ischnodes sanguinicollis and Oedostethus quadripustulatus) which may be potentially doubtful. Neither are currently listed on the NBN Gateway.

RDB1: Endangered. Species which have shown a rapid continuous decline over the last twenty years, and now exist in 5 or fewer 10km squares of the national grid. RDB2: Vulnerable. Species likely to move into RDB1 in the near future, as most or all populations are declining. Found in 15 or fewer 10km squares since 1980. RDB3: Rare. Species with small populations which are localised or thinly scattered, but not at present qualifying for RDB1-2. Found in 15 or fewer 10km squares since 1980. RDBK: Species believed to be rare but too recently discovered to be categorised easily. RDBI: Red data book indeterminate. Species believed to be rare, but for which data on their distribution is insufficient to allow a grade to be assigned. Na: Nationally Scarce Grade A. Recorded in 16-30 10km squares since 1980. Nb: Nationally Scarce Grade B. Recorded in 31-100 10km squares since 1980.
