A very rare species in Belgium. It is probably less reported due to the large overlap with other similar mines on Quercus.
Native
The mine is a relative short gallery with a broad frass line.

The cocoon is reddish brown.
The egg is deposited on either side of the leaf, away from the margin.
There are two generations a year. Adults are on the wing from April to May and from the end of July to late September.
Only found on Quercus species.
