Taeniopteryx maura

Taeniopteryx maura (Pictet, 1841) Notes Taeniopteryx maura is commonly referred to as the Spinyleg Willowfly (Stark et al. 2012). The distribution of this species extends from southeastern Canada southwest to Tennessee and Mississippi, and further west to Oklahoma and Texas (Stewart 2000, DeWalt et al. 2024). In southern Quebec, this species displays a univoltine-fast life cycle with a diapause period during the summer and early autumn (Harper et al. 1991 b). Adults of this species are commonly encountered from mid-March to early May (Fig. 22) from a wide range of elevations (31-582 m asl; Fig. 23) in both small streams and large rivers across the state (Fig. 24 f).
