For the first time recorded from Belgium at Maasmechelen (LI) in 2019, confirmed by examination of its genitalia. This species can easily be confused with its congeners Pseudotelphusa paripunctella and Teleiodes wagae and the genitalia should be studied. The species is mainly known from the southern parts of Central Europe, though not from most of the Mediterranean countries.
A healthy population is present in some heathland areas in LI.
Take a look at Pseudotelphusa paripunctella for differences with P. aenigma.
The larva usually spins two leaves together and constructs in this shelter a silken tube from where it feeds. It eats only the unexposed part of the parenchyma so at not to expose its presence.
Probably two generations a year, difficult to separate: from late April to August.
