Most flies examined were col- lectedoti Teiierifeand Gomera, and thereis little in- Iortiiatioii ironi thc two descrt islaiids Fucrtevcii- iiiIa aiid Laiizaiote (Frcy 195ki). To characterizc each species froiii tlie ecological poiiit of vicw, tlie plaiit coiiiniuiiity for each record was iioted. According to Oberdorfer (1965) five plaiit coiiiiiiunities wcre recognized: semi desert slii-u b--coiii ni ii iii t y (-v~op/iy//ur>t-%o//;~o~eriu coiiiiiiuiiity). succuleiit shrub-coiiiiiiuiiity (Klci- rtiu-Euphorbiori), lauropliyll forest (Lourion mucuroriesiuiri). piiie forests (/+!->ion curiuriense) aiid siibalpiiic slirub-coiniiiuiiity (Rc/wtiu co~niiiu- iiity). For tliis stiidy two additional coniiiiunities werc distiiiguishcd: uiiciiltivatcd arcas with thistlcs (Gu/uc/iles -Curc/utcs coiiiniuiiit y) aiid ciilt ivatcd arcas (oraiiges, baiiaiias, hotel gardcns).
