The larva of the species on jojoba occurs in the fruit and is found at several locales (Table I). One to 3 larvae may infest a single fruit. Infested fruit are small, usually 7mm or less in length, never develop fully, but eventually dry and drop. The presence of the feeding larva is indicated by a slight swelling of the adjacent fruit wall. Pupation takes place in the fruit. The adult eventually escapes from the pupal skin leaving it attached(Fig.I). Infested fruit are most abundant in winter and early spring, before the general blooming period for jojoba at Radec. At this time most of the fruit found are those harboring Asphondylia, suggesting
that midge oviposition or larval feeding causes premature and abnormal development.
