 Ephydridae larvae and pupae are characterized by breathing tube bifurcate at end. The length of the tube is relatively different among genera.
The first - Paracoenia fumosa (body length 5 mm without tube) - has the longest one in this family

 I have some pupa (and larva) too with shorter and longer brething tube, like this the one, of which I think is Dichaeta caudata

 or even shorter breathing tube, but with characteristic thoracic patttern (Pelina)

 Or even without breathing tube but with two posterior spines, which are used to pierce the parenchym. In this case a Hydrellia spec piercing Lemna gibba. By the way, this is the smallest Hydrellia I have ever seen, normally (in The Netherlands) they are twice this size. Most often (or always) Hydrellia spec. prefer one type of macrophyt and in this case probably restricted to Lemna.

 Or a pupa with more dorsally placed (but short) breathing tube, like in this Nostima spec.

 Resembles Scatella (Neoscatella) clavipes and S.(N.) warreni if compare with figures in Ferrar, 1987. Both Australasian/Oceanian....
Possibly something less exotic (crassicosta for example: who has long face possibly has long tube branches)

 This unknown pupa (last photo) was collected exactly at the Dutch/Belgium border in a stream called Noordermark. It looks also something like Parydra coarctata, which suppose to occur in The Netherlands.

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
