Gordius dimorphus larvae are similar to previous light microscope descriptions. One large spine is present on the posterior portion of the postseptum. On the surface of each projection, 3 pairs of aculeiforms spines are aligned and lean toward the proboscis opening. The proboscis is retractile, dorsoventrally flattened, with 1 pair of forceps-like projections on its distal-most portion.

However, epibenthic aquatic larvae and their terrestrial definitive hosts do not overlap in habitat. Three concentric rings with 6 spines each surround the proboscis. ARTICLE FIGURES & TABLES REFERENCES CITED BY Abstract To complete their life cycle, gordiids must make a transition from aquatic to terrestrial environments. Larvae have a cylindrical body, annulated and divided into 2 sections, plus an anterior preseptum and a posterior postseptum. LIFE HISTORY AND DEVELOPMENT: Hairworms are parasitic as juveniles and. dimorphus (2 males and 1 female) were maintained under laboratory conditions until oviposition, which occurred within long strings commonly referred to as egg strings. HISTORY: Nematamorpha worms were first noted in the 14th and 15th centuries. Scanning electron microscopy was used to analyze superficial features of Gordius dimorphus Poinar, 1991, larvae that might serve as generic or specific diagnostic characters.
