Gordius dimorphus larvae are similar to previous light microscope descriptions. Biodiversity research combines two dimensions, the horizontal one that contains species diversity, patterns among this diversity and its interconnections and the vertical one that deals with the history of biodiversity, i.e., its phylogeny.
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. Three concentric rings with 6 spines each surround the proboscis. Larvae have a cylindrical body, annulated and divided into 2 sections, plus an anterior preseptum and a posterior postseptum.
Feeding All nematomorphs derive all their nutritional requirements as internal parasites of insects: the stages found outside the host do not feed. dimorphus (2 males and 1 female) were maintained under laboratory conditions until oviposition, which occurred within long strings commonly referred to as egg strings. The life cycle may be between about a month and a year. Scanning electron microscopy was used to analyze superficial features of Gordius dimorphus Poinar, 1991, larvae that might serve as generic or specific diagnostic characters.
