<p>An unidentified mermithid species parasitizing Ochlerotatus cantons is presented, being the first mosquito-parasitic&nbsp;mermithid recorded from Denmark. The parasitic development is initiated in the larval host, continues in the pupa and is completed in the abdominal haemocoel of the adult, the mean body length of the parasite increasing from&nbsp;about 1mm to 12-13 mm. From 1 to 5 mermithid worms were found per adult host. Up to 87% of male and female&nbsp;mosquitoes hatched in the laboratory or swept in the herbaceous layer surrounding woodland pools were parasitized.&nbsp;The prevalence of the parasite varied between pools.</p>
