Dasineura trifolii


    Dasineura trifolii is a midge whose larvae cause galls on the leaves of Clover and especially White Clover. The gall forces the leaflets to fold upwards along the midrib therefore creating a pod-like structure. Just above the fold the gall takes the form of numerous red and green swellings that run the entire length of the leaf. Each gall holds one or two larvae that start off white and become more orange as they mature.
