Larval host plant(s): Agrostis sp., Deschampsia cespitosa (L.) Beauv., Festuca sp., Holcus sp., Phalaris arundinacea L. ( Poaceae ), Carex sp. ( Cyperaceae ) ( Stainton 1858b; E. Hering 1891; Sønderup 1949; Wörz 1957; Buszko 1989b; Parenti & Varalda 1994).

Figs.: Traugott-Olsen & Nielsen (1977), Biesenbaum (1995), Bland (1995).

Remarks: Joannis (1915: 104) considers Elachista macquartella Duponchel, 1840: 550 , pl. 309 likely conspecific with E. humilis Zeller, 1850 but refrained of formally synonymizing the two. In accordance to ICZN (1999: Art. 23.9.1), this name should not be taken into use as the senior synonym of E. humilis because it has not been in use since its original description, and the usage of the name E. humilis meets the requirements of Art. 23.9.2. The name Elachista macquartella Duponchel, 1840 is considered a nomen oblitum, stat. nov. The host plant records, except for Deschampsia cespitosa (L.) Beauv., should be verified, as E. humilis has frequently been confused with E. canapennella and E. freyerella in the past.
