Amauromyza chenopodivora Spencer, 1971

mine

The larva bores in the pith of the stem, and eats this out while descending as low as the root collar. But before that it makes a linear mine in the green rind of the stem. Occasionally oviposition takes place on a leaf, leading to a fine corridor (withou frass) running towards the midrib, and from there to the stem. The place where the larva finally exits the stem for pupation is indicated by a red-ringed hole.
