They're very skinny white worms
Four or five of these were crawling about on the bottom of a small artificial freshwater pond.
Not sure what the host insect would have been, but there was a big dead cockroach Drymaplaneta sp. in the pond.
Poor nematode! He got stuck on some organic matter -- he is really having a bad day! The coordinates for this observation are inaccurate and have to be re-done.
Nematode which is squirming dramatically.
On a fallen log in podocarp-broadleaf forest. Waving front portion of body around, then crawled down to ground. About 100mm long.
Trichuirs vulpis, identificado mediante exámen coproparasitocospico en un cerdo.
Mermis nigrescens (Nematoda: Mermithidae) a parasitic nematode of the European Earwig Forficula auricularia (Dermaptera: Forficulidae). Image is of an adult female, the sex evident by the presence of the brownish string of eggs within the transparent body. Following substantial rain the female seeks a plant high point and lays its eggs on leaf tips. Species was identified through genetic analysis for a published paper titled: Morphological and molecular characterisation of Mermis nigrescens Dujardin, 1842 (Nematoda: Mermithidae) parasitising the European earwig (Dermaptera : Forficulidae) in New Zealand.
