Agromyza nana: mine on Melilotus cf officinalis

Melilotus cf officinalis, Amsterdam Noord, JH Vliegenbos: mine with pupa of parasitoid

mine

Broad and short hook-like upper-surface corridor, ending in a blotch in the centre of a leaflet. The blotch is upper-surface as well, but has some deep spots, giving the mine a mottled appearance when hold against the light. Frass in the blotch in a few large lumps. Pupation outside the mine.

hostplants

Fabaceae, oligophagous

Anthyllis; Lotus ornithopodioides; Medicago falcata, lupulina, minima, polymorpha, sativa, truncatula, varia; Melilotus albus, altissimus, messanensis, officinalis; Onobrychis viciifolia; Securigera varia, securidacea; Trifolium alpestre, campestre, fragiferum, hybridum, incarnatum, medium, montanum, ochroleucon, pratense, repens, stellatum; Trigonella; Vicia cracca, dumetorum, hirsuta, sativa, sylvatica.

The reference to Oxalis by Benavent, Martínez, Moreno & Jiménez (2004a) and Gil Ortiz (2009a) must be a mistake – in the vegetative state confusion with Trifolium can be imagined. Also some old references to Genista are not very probable.

phenology

Larvae from June to October (Hering, 1957a).

BENELUX

synonyms

Domomyza nana; Agromyza medicaginis Robineau-Desvoidy, 1851; A. trifolii Kaltenbach, 1872; A. anthracipes (Rondani, 1875); A. brevinervis (Rondani, 1875).

notes

The full-grown larva remains without feeding for one or two days in the centre of the mine, before leaving it for pupation (Spencer, 1976a).

Very occasionally a pest on clover and alfalfa (Darvas, Skuhravá & Andersen, 2000a: Spencer, 1973b).

The mine can easily be confused with the one of the much rarer Parectopa ononidis; see there for differentiating characters.
