Lestodiplosis
Kieffer, 1894
Lestodiplosis is a of in the . in this genus are predatory rather than -feeding, with at least one documented species, Lestodiplosis xylodiplosuga, preying on other gall midge that inhabit freshly cut wood. These tiny are part of a complex associated with xylophilous (wood-dwelling) cecidomyiids in Europe and potentially North America.

Identification
Lestodiplosis are minute , typically around 1 mm in length, consistent with other . Distinguishing Lestodiplosis from other cecidomyiid genera requires examination of morphological characters such as , , and under high magnification. The genus is not readily identifiable from field photographs alone.
Habitat
Associated with freshly cut wood and xylem vessels of recently damaged or felled trees, particularly oak. The is defined by the presence of wood-boring or wood-inhabiting that serve as .
Distribution
Documented from Europe (Denmark, Norway, Sweden) based on GBIF records. Ecologically similar involving Lestodiplosis have been observed in North America (Kansas, USA), though specific identifications remain uncertain.
Seasonality
Activity coincides with periods of tree damage and fresh wood exposure. In the documented Kansas observation, were present in late June following branch breakage and subsequent sawing of oak limbs.
Diet
Predatory. Lestodiplosis xylodiplosuga has been documented feeding on of Xylodiplosis that inhabit xylem vessels of fresh-cut wood.
