I have a specimen (possibly Dipteran...not sure) collected August 2008 from the Torngat Mtns in northern Labrador, Canada .
The sample is an aquatic invertebrate sample, but may have had some by-catch in net from stream side vegetation.
The specimen is an adult almost 1 mm long.
The 2nd pair of wings are very reduced and end in a thin thread (see picture). The front wings have 2 veins. The end of the abdomen ends in a single point. Antennae is long (filiform) with about 10 segments all similar sized. Mouthparts are chewing. Doesn't seem to be an Ephemeroptera.
I'd appreciate any tips people can give me. Thanks.

There is at least one fly without a club on the halter:
Diaphanobezzia (Ceratopogonidae). I don't think that's what you have. The illustration does not look like your picture and I don't know if it occurs in Canada.

It's a male scale insect (google for images, and you'll find a match)

That was my idea, too, but they do not have chewing mouthparts (though they may easily be mistaken for them).

Sorry for the poor picture, but hopefully you can get an idea.

I posted the whole body picture.
Thanks for the ideas...I will check out the scale insect.
I definitely could have mistaken the mouthparts...
Thanks,

I think it's not Diptera, maybe Hemiptera (Homoptera in part)???

Male scale insects, just like Tony said.
