Poinar (1987) did not rule out that some spider mermithid species may also have a direct life cycle.
For example, winged, flying insects are more likely to be consumed by web spinning or foliage/flower hunting spiders than they are by non-web spinning, ground hunters or burrowing, sit and wait predators, which can be expected to feed primarily on non-flying, mainly fully terrestrial prey and are thus, more likely to be hosts to mermithids with a direct life cycle.
The large number of non-web spinning, cursorial Lycosidae (Table 1; 38% of all species, excluding nomina dubia) with undescribed mermithids, suggests that a direct life cycle may be involved in some instances.
