Leaf-mine: A large, irregular blotch mine with a short linear section in the first instar which is frequently entirely enveloped in the fully developed mine and may then be no longer visible (Spencer, 1976: 124).

Perhaps the only character differentiating it from abiens is the presence of several larvae in a fully developed mine of abiens and just one in myosotidis (Bladmineerders van Europa).

Larva: Details unknown.

Puparium: Reddish-brown; posterior spiracles each with 3 bulbs (Spencer, 1976: 124).

Hosts in Britain:

Hosts elsewhere:

Time of year - mines: July-August, October.

Time of year - adults: September.

Distribution in Great Britain and Ireland: Widespread in Britain including Hampshire (Barnet), Oxford (Oxford), Suffolk (Dunwich), Denbighshire (Cefn-y-bedd) (Spencer, 1972: 35) and Warwickshire (Corley and Coventry) (Robbins, 1991: 97); Cambridgeshire (NBN Gateway - N.B. includes Watsonian Vice Counties having publicly available records that fall within or overlap the vice county border at 10km resolution or better i.e. a record for a vice county may relate to an adjacent vice county - for included datasets see NBN Grid map below).

Distribution elsewhere: Widespread in continental Europe including Denmark, Germany, Poland, Sweden (Spencer, 1976: 124) and the [former] U.S.S.R. (Mines in BMNH), Austria, Belgium, Canary Is., Czech Republic, French mainland, Spanish mainland and Switzerland (Martinez in Fauna Europaea).

Also recorded in Ethiopia (Spencer, 1976: 124).
