status

 

Agromyza reptans Fallén  

Material examined. MASSACHUSETTS: Franklin Co., Northfield, 276 Old Wendell Rd. , 22.x.2017, em. 30.iv.2018, C.S. Eiseman, ex Urtica dioica   , # CSE4459,   CNC1144082 View Materials (1♀)   .

Host. Urticaceae   : Urtica dioica L.  

Leaf mine. Blackish, with paler greenish-brown patches only in the newest portions where the larvae are actively feeding; initially narrow and following the leaf margin, later expanding to a broad blotch. Frass is partly diffuse and partly in irregular lumps.

Puparium. Reddish-brown; formed outside the mine.

Phenology and voltinism. This species has at least two generations per year; it has not been observed to have a summer pupal diapause as observed in A. pseudoreptans   , but there is evidently some variation in length of the pupal stage. Spencer (1969) listed a specimen emerging on 14 August from a larva collected on 5 June in Ontario, whereas Eiseman & Lonsdale (2018) listed specimens emerging on 21 July from larvae collected on 28 June in New York. The larvae from which our Massachusetts specimen was reared were found on 22 October, a few days before larvae of A. pseudoreptans   appeared several meters away.

Distribution. USA: CA, *MA, NY, WA; Canada: ON, QC, SK; Europe; Kazakhstan; Turkmenistan ( Nartshuk & von Tschirnhaus 2017; Eiseman & Lonsdale 2018).
