size data unrealistic:
3.3 mm means that the grass blades are under 0.5 mm wide; please correct

Standard size
Commonly used sizes for flies are wing length and body length, i.e. head+thorax+abdomen exclusive of antennae.

okay, thanks--
not sure dipterists use such a measurement routinely, do they? [although i completely agree that the measurements of hard parts, such as thorax or head, are more reliable than body length that includes the abdomen which may extend/contract]
size data may only help identification if they reflect the parameters conventionally used in reference literature.
now you have to edit every submission form of the series to avoid confusion :/
suggest leaving the size field blank: the measurement is an estimate anyway
