Marsh Fly

Sepedon aenescens Wiedemann

Description:

Approx. 8~12mm. Very similar to Sepedon found in the West, but once source says that the oriental population has been classified as a separate species based on coloration, male genitalia, etc: http://www.nativefishlab.net/library/tex... (p. 57). That source also mentions S. violacea as a possibility, but since my photos don't have enough detail, it is futile to try to distinguish it further.

Habitat:

Low low to medium grasses.

Notes:

I thought Penthetria or Bibionidae were possible, but am not familiar enough with them to figure it out.

Great! It does have some differences in coloring from S. sphegea.

So far, I've found Sepedon aenescens Wiedemann in China and "the orient" in: http://www.gbif.org/species/120374278. If I can't find S. sphegea this far east, I guess I'll have to go with that.

That looks dead on, Lauren! Thanks! I'm going to track down its range and verify that it's here in Korea (or what variety there is here), then I'll edit the spotting. Many thanks! :D

Wow great info thanks Lauren.. so it's slugs that need to watch out for those incredible face gadgets. Incredible!

This looks like a fly of the Family Sciomyzidae, maybe a species Sepedon, if not actually S. sphegea itself…..It is called the Slug Killing Fly.....http://www.diptera.info/forum/viewthread.php?thread_id=56423, http://es.treknature.com/gallery/photo29....

Yeah I think iincidenthey are incidental specks. Maybe someone will have some input soon. I am out for a while.

Maybe it's just accidental specks of something.. what do you think? Certainly seems to be in the right location. but as you say most else seems dipteran. Let's hope an expert sees it.

OK, I added a super super crop of the head.

AudieWilkins

I'll get the original out and see if I can't crop it further...

great head shot btw... maybe I'm imagining the ocelli

Sadly, it flew away before I could get in position for another aspect. Bummer.

Mark Ridgway

....but I can't get around those antennae !? It seems to have 3 ocelli on it's head though... very interesting. Got a top view?

AudieWilkins

With those antennae, thick waist, coloring and body hairs? That would have to be a pretty atypical Vespid, I think. I'm no expert, though.

I think it's a type of wasp Audie.
