Phytomyza penicilla Hendel, 1935
In fact a borer, rather than a miner. The larva tunnels in the midrib, causing it to swell gall-like, mainly in its basal part. Sometimes the larva makes excursions into the blade. Pupation within the leaf.
Possibly also Arctium (Spencer, 1973b).
Larvae in the leaves in April-May. There is a second generation in summer, in which the larvae bore in the stem and roots (Spencer, 1973b).
