other Scaptomyza 

Only a few of the remaining Scaptomyza  subgenera have rearing records. The subgenus Exalloscaptomyza  is highly specialized on the ephemeral flowers of morning glory ( Ipomoea  , Convolvulaceae  ). This is a habitat utilized by other continental drosophilids, including D. floricola  which has been introduced to Hawai‘i. Exalloscaptomyza  females are unusual in laying a single, well-developed egg or first instar larva ( Kambysellis & Heed, 1971) and have among the shortest development times of all Hawaiian Drosophilidae ( Heed, 1968)  , both adaptations to a short-lived substrate.

Titanochaeta  has taken an unusual path as a predator of spider egg sacs. The pointed, sclerotized ovipositor they use to pierce the sac is characteristic of the group. Although a fair number of them have been reared, including 6 of the 11 species, little is known of their habits and they are uncommon in collections. Predation is also found in other drosophilid groups, especially the Steganinae  , but rarely in Drosophila  or Scaptomyza ( Ashburner, 1981)  , although the Pisona– breeding Elmomyza are also predators.

The only other Scaptomyza  subgenus with a moderate number of rearing records is Tantalia  , which breed largely on leaves but do not appear to be host-specific, even within a species. Bunostoma  has too few rearing records to draw even preliminary conclusions, and only one of the 8 unplaced species originally described as Drosophila  but probably belonging to Scaptomyza  ( D. vinnula  ) has been reared. The other Hawaiian Scaptomyza  subgenera – Alloscaptomyza  , Celidosoma  , Engiscaptomyza  , Grimshawomyia  , and Rosenwaldia  – lack any data at all.
