Hello megalopteran, welcome to the forum. It is most likely genus Chironomus but for that you need to check if the penultimate segment has ventral tubules. Or add a photo of the end of the larva. If it doesn't have tubules you have to add a detailed photo of the ventral side of the headcapsule. |

2 pairs are even unique for Chironomus spec. There are some species with a reduced pair or even 1 pair. Some other genera can have 1 pair too and consequently resemble Chironomus. But this is Chironomus and almost impossible to identify to specieslevel. I know some European keys and the one by Epler from NA. |

In America we also have Goeldichironomus which is related to Chironomus. According to Epler's paper, it can have 2 pairs of ventral tubules. |

Thanks for the info, I've never delved into Diptera as I see colleagues going crazy identifying them lol. Thanks. I'll take the info and keep digging. |
