Remarks: E. taeniops is one of the commonest and largest of the Egyptian Syrphidae (Efflatoun 1922) . Adults come to the edges of small streams to drink during hot weather. They usually visit flowers of Eryngium, Euphorbia, Hedera, Mentha, Rubus, Senecio and Solidago (Marcos-García 1985; Speight 2017). The rat-tailed larvae feed in water polluted by decaying organic matter, such as sewage treatment ponds (Mahmoud et al. 1999).
