Mutants have smaller wings than normal.
Both the anterior and posterior wing are severely reduced in hemizygotes, wing vein L4 is shortened, and wing vein L5 and the alulae are absent. The submarginal cell (between L2 and L3) appears relatively normal. In some wings the costal cell is extended and wing vein L1 reaches the wing margin more distally than normal. The triple row is reduced in the dorsal rows but not the ventral row. elA1/Df(2L)b83d29a adults are wild-type. elA1/Df(2L)b84a2 adults have an "elbow" phenotype.
Strong; class i (Davis, 2003.5.6, personal communication to FlyBase provides contradictory, class ii, assignment).
