Found an unknown pupa of a fly on 14.v.2018 when sweeping with a pondnet in a waterbody named 'De leiding' just west of Witharen (Overijsel), The Netherlands. It wasn't an aquatic fly (I'm an aquatic biologist), nevertheless the shape of the pupa and the peculiar anterior spiracles (with numerous pores) intrigued me, and I tried to rear it. After about a week the adult emerges (somewhere around May 20) and photographed it too.
As I have no idea what family it is and the pupa is unfamiliar to me, I would like it very much if anybody has a clue.
I don't need it, so if you like, I can send it, it is still alive and kicking on my desk. I think I will preserve it in ethanol tomorrow.
On Waarneming.nl Agromyzidae was suggested, but uncertain. The fly is 2.7 mm long. The pupa is probably an accidental catch from vegetation and is terrestrial.
Thanks

Hi Ton,

Yes, a Agromyzidae, Agromyzinae. It looks like a male to me. Agromyzidae females have a quite distinct ovipositor. Males have small genitalia.

Greetings,

Agromyza alunulata (Hendel, 1931) (Agromyzidae), male (synonym: A. distorta Griffiths, 1955), monophagous leaf miner on Glyceria maxima. A rarely reported species with peculiar anterior spiracles as adaptation to an aquatic environment. Over 200 spiracular bulbs are distributed over the whole surface of each large plate-shaped spiracle. At least the winter puparia end up in water as they are only loosely attached to the leaf surface. Only one further world agromyzid, the East Asian/Japanese rice miner Agromyza oryzae Munakata, 1910, is known with similar anterior spiracles. Summer and winter puparia are dimorphic, a second rare peculiarity among Agromyzidae. Griffiths (Tijdschr. Ent. 106 [1955]: 113-168) observed that larvae can crawl and pupariate underwater being equipped with special bristle-like spines on the ventral locomotory humps. First record for The Netherlands, species known only from Czech Republic, Denmark, England, Finland, France, Germany, Hungary, Lithuania, Poland, Russia, Sweden, and Turkey. 48 papers deal with the species and its parasitoids.

That's excellent news!
What a comprehensive answer, Thank you very much.
Pupal skin and adult should be in Milos Cerny's collection now.

Hi Ton,
very thanks for pupal skin and male specimen.
Yes, Agromyza alunulata, one note, also recently recorded from China.

Some flies preserved in ethanol and then pinned often get the eyes sunken, how can this be avoided? Best answer: I usually keep alcohol-collected material in alcohol

Yes, dipterologists from far abroad, please buy your copy at veldshop. Stamps will be expensive, but he, the book is unreasonably cheap Smile
