Hemolymph, or haemolymph, is a fluid, analogous to the blood in vertebrates, that circulates in the interior of the arthropod (invertebrate) body, remaining in direct contact with the animal's tissues. It is composed of a fluid plasma in which hemolymph cells called hemocytes are suspended. In addition to hemocytes, the plasma also contains ...
The main function of insect blood, hemolymph, is that of transport and it bathes the insect's body organs. Making up usually less than 25% of an insect's body weight, it transports hormones, nutrients and wastes and has a role in osmoregulation, temperature control, immunity, storage (water, carbohydrates and fats) and skeletal function.
Paederus dermatitis, medically known as dermatitis linearis, [1] is a skin irritation resulting from contact with the hemolymph of certain rove beetles, a group that belongs to the insect order Coleoptera and the genus Paederus.

After skin comes in contact with cantharidin, local irritation begins within a few hours. [3] ( This is in contrast to Paederus dermatitis, where symptoms first appear 12–36 hours after contact with rove beetles.) [4] Painful blisters appear, but scarring from these epidermal lesions is rare.
