Species calverti Muttkowski, 1910 [Tramea]
This tropical species has expanded its northern range into Texas. It has a pale yellow face that turns red in mature males and the vertex is metallic violet. The thorax is brown with 2 oblique pale stripes laterally. The wings are clear with a broad basal brown stripe in the hindwing. The legs are pale basally and darker beyond. The abdomen is yellowish in females and red in mature males. Segments 8-10 are black dorsally.
Total length: 44-49 mm; abdomen: 30-33 mm; hindwing: 37-42 mm.
This is the only saddlebag glider in the region with a striped thorax. It is most similar to the smaller Hyacinth Glider (Miathyria marcella), but it lacks the complete middorsal black stripe on the abdomen of that species.
Temporary and permanent ponds and slow streams.
This species has been found as far north as New York and Massachusetts. It is widely distributed in Texas, but is most commonly encountered in the southern portions of the state. It is typical of the genus in having a strong steady, high flight, often not coming below two meters. They will perch horizontally at the tips of tall grasses and branches with a clear view of intruders in open fields and around ponds. The female lays eg gs in a manner typical of the genus, as previously described.
