All asymmetrical with elaborate heads and various combinations of warts, scales and setae.  Small nematodes.  Usually found in natural, rather than agricultural, environments.

Many nematode species of the Bunonematoidea appear to have phoretic relationships with insects, particularly insects in the order Coleoptera and family Scarabaeidae. The type of phoresy may be interpreted from the insect body parts invaded by the nematodes and the elaborate cuticular ornamentations and extracuticular deposits of the nematodes that apparently aid their survival in the stressful environments of the insect body (Nazir et al., 2019).
