Lauxaniid Flies

From last year: a pair of Lauxaniid flies (Diptera: Lauxaniidae) mating on a nettle leaf.  I don't know the species nor the genus.

Some differences between Linnaemya picta and Linnaemya tesselans

This year I have collected many specimens of Linnaemya picta but, so far, only one Linnaemya tesselans.

Here are some photos that illustrate two of the differences between these two species.

L. picta (also L. rossica):  "Gena with larger black hairs/small bristles - some of which are at least half the thickness of the bristles below the vibrissa":

L. tesselans:  "Gena with only fine hairs (at least some of the lower ones also fair) - distinct from the single line of bristles extending down from the vibrissa":

L. picta (also L. rossica):  "Costal cell with a uniform covering of microscopic hairs":

L. tesselans:  "Costal cell of the wing with only approximately half its area covered in the microscopic hairs found over most of the wing":

Anthomyiid Fly

What I think is a male Anthomyia plurinotata (Diptera: Anthomyiidae).  Identified by comparing the pattern on the top of the thorax with the patterns in this post at

This is the second member of this species I have come across: in the spring of 2013 I photographed a female (see here).
