Hungarian Glider Butterfly Neptis rivularis

The Hungarian Glider is found from central and eastern Europe through Russia and Central Asia to Japan in the Far East. Its range is similar to that of the larger Common Glider (Neptis sappho) of Eastern Europe, Russia, India and the Far East. The names "Glider" and "Sailer" come from the slow, drifting flight. These were in Kazakhstan's Tian Shan mountains. The similar Limenitis helmanni, 60-65mm wingdpan, less straight white bar and lighter ginger underside flies in the same area. The Common Sergeant (Athyma perius) is present in the Himalayas and South and Southeast Asia.

The Hungarian Glider has one strong white bar on its dark brown topside and 1-2 weaker lines. The Common Glider and Common Sergeant have three strong white bars. The Hungarian Glider has a medium rufous brown underside; the Common Glider has dark brown and the Common Sergeant has light orangey brown. The Hungarian Glider has a wingspan of some 58-65mm compared to 40-46mm for the Common Glider and 50-60mm for the Common Sergeant.
