Belongs within: Bibionomorpha. The Pachyneuroidea are a group of flies in which the adult mandibles are absent, the antennal pedicel is slightly enlarged, and the base of wing vein M is oblique. Larvae have mandibles which move horizontally (Blagoderov et al. 2002). Living members of this clade are divided between the Pachyneuridae, long-legged flies with… Continue reading Pachyneuroidea


Belongs within: Bibionomorpha. The Scatopsoidea are a clade of flies united by wings with M1+2 fused to Rs for a distance, and M3 and im lost; at least living species also have the larval head greatly reduced (Blagoderov et al. 2002). Members of the Scatopsidae have a single-segmented palpus and five to ten antennal flagellomeres… Continue reading Scatopsoidea


Belongs within: Sciaroidea.Contains: Macrocera, Platyura. The Keroplatidae is a group of fungus gnats whose larvae live in webs or mucous tubes in secluded habitats. Larvae feed on fungal spores or small animals caught in the web. The glowworms Arachnocampa of Australia and New Zealand produce light to lure prey; some Keroplatinae are also luminous. The… Continue reading Keroplatidae


Belongs within: Neoneura.Contains: Scatopsoidea, Pachyneuroidea, Sciaroidea. The Bibionomorpha are a clade of flies supported by molecular data, including the gnats and related taxa. Members include the wood gnats of the Anisopodidae whose saprophagous larvae have a characteristic vigorous serpentine movement (Hancock & Amorim 2009). <==BibionomorphaWT11 |–+–+–ScatopsoideaWT11 | | `–Valeseguya [Valeseguyidae]GE05 | | `–V. disjunctaGE05 |… Continue reading Bibionomorpha


Belongs within: Sciaroidea.Contains: Lestremiinae, Porricondylinae, Cecidomyiinae. The Cecidomyiidae are a group of minute flies commonly known as gall midges though gall-forming members of the family are restricted to the subfamily Cecidomyiinae. Members of the subfamilies Porricondylinae and Cecidomyiinae lack ocelli and have shortened first tarsomeres, distinguishing them from the more plesiomorphic Lestremiinae and Catotricha. Characters… Continue reading Cecidomyiidae


Belongs within: Sciaroidea.Contains: Sciara (Sciara). The Sciaridae, fungus gnats, are a group of small flies that mostly feed on decaying organic matter. They are characterised by wings with a short costa, a single short crossvein r-m near the base of the wing, two strongly sclerotised R veins and weakly sclerotised forked M and Cu veins… Continue reading Sciaridae


Belongs within: Cecidomyiidae. The Porricondylinae are a group of midges whose larvae are mostly mycophagous in decaying wood and vegetation though some may secondarily invade living plant tissue (Gagné 1981). Midges of the macabre Published 12 March 2017 In a recent post, I commented that derived members of an insect ‘order’ could sometimes be all… Continue reading Porricondylinae


Belongs within: Cecidomyiidae. The Lestremiinae are a group of cecidomyiid midges with mycophagous larvae (Gagné 1981). Characters (from Gagné 1981): Ocelli usually present. Wings, if present, with vein M1+2 present. Five tarsomeres, with tarsomere 1 longer than 2. <==LestremiinaeJ00 |–LestremiiniGJ09 | |–Wasmanniella claudaG81 | |–GongromastixG81 | |–AllareteG81 | |–Anaretella defectaG81 | |–Pararete elongataG81 | |–ConareteG81… Continue reading Lestremiinae


Belongs within: Cecidomyiinae. The Oligotrophini are a group of midges whose larvae cause galls or live freely in flower heads (Gagné 1981). Members include the Hessian fly Mayetiola destructor, a serious pest of wheat crops in many parts of the world. Juniper gall midges Published 1 January 2016 Sometimes, the evidence of an insect’s presence… Continue reading Oligotrophini


Belongs within: Cecidomyiidae.Contains: Oligotrophini, Alycaulini, Contarinia, Asphondyliini. The Cecidomyiinae are a diverse group of midges, many of which cause galls in plants but which also include non-galling phytophagous, mycophagous and predatory forms (Gagné 1981). They are divided between four supertribes, of which the Cecidomyiidi are characterised by male genitalia with parameres rudimentary or absent, as… Continue reading Cecidomyiinae
