Hi people,
I am trying to figure out this larva, but with the identification keys it is very hard. It should be easy because it has a distinct rod shape and slim head compared to other taxa in my samples.
It was found in North East Friesland (Netherlands) in a brackish canal leading to the Lauwersmeer.
Family would be satisfying enough. Genus/Species would be wonderful.
Is anyone able to help me out, and what identification pointers you used to arrive at the conclusion?
Thanks!
It seems to be Sphaeromias sp. though I can't be sure. Is it possible for you to post a higher magnification picture of the head and posterior end of the abdomen (anal portion). If mounted for instance then you might get a better picture using compound scope. If can't no worries but higher magnification and better lighting may help.
As the others have mentioned, definitely Ceratopogonidae. The long, cylindrical body with the reduced hard capsule is a pretty big giveaway. There are several other groups with a a similar overall structure, but they also possess features that quickly separate them out.
I'll be happy to look at it if you can send the specimen to Fort Collins. And thanks again for all the information you have provided about WY gastropods.
It could be larvae of Culicoides or Ceratopogon. You should makes trap for the adult species
