This species is the largest springtail in the UK (3). The antennae are longer than the body when straight (2) but curl into spirals from the tip when the specimen is disturbed (3). The body is covered in tiny scales which give this insect a dark appearance, but the cuticle below the scales is golden or brown (2). Springtails are an ancient group of small, wingless six-legged insects in which the mouthparts are situated inside the head (3). The name ‘springtail’ refers to the fact that most of these insects have a forked appendage beneath the abdomen known as the furca. The furca is usually tucked away but can be sprung open rapidly, flinging the insect into the air (3). All springtails have a tube beneath the abdomen which secretes ‘glue’; this tube is important in grooming and allows these insects to cling onto smooth surfaces. This feature has earned this group the name Collembola, from the Greek words ‘cole’ meaning glue and ‘embolon’ meaning piston (3). Springtails are the most abundant insects in the world, and are found in huge numbers in nearly every habitat
