Following Heath (1986), M. jacobella is known only from Morocco and Tunisia. Most probably, it may be found also in Algeria. So far, the species has been recorded only near sea-level (Kurz & Kurz 2011).


There aren´t any data available about the biology of M. jacobella. Imagines have been found on the wing in March and April (Heath 1986, Kurz & Kurz 2011).

Stages in development:

The early stages are unknown.
