Ceratitis cosyra, een Afrikaanse boorvlieg gevonden in Drenthe (Diptera: Tephritidae)

Ceratitis cosyra, an African fruitfly found in the Dutch province of Drenthe (Diptera: Tephritidae) A single specimen of Ceratitis (Ceratalaspis) cosyra (Walker, 1849) was collected near Papenvoort (utm ld4768) with a malaisetrap in the period 4-6 september 1993 (leg. L. Witmond). Up till now it was believed to be one of the few specimens of Ceratitis capitata (Wiedemann, 1824) collected in the field in the Netherlands. Re-examination of the specimen revealed it’s true identity. Both species are very similar except for the colour-pattern on the thorax which is illustrated for both species.
