NOTES ON THE DISTRIBUTION AND BIOLOGY OF TRAPEZITES GENEVIEVEAE ATKINS, SIGNETA TYMBOPHORA (MEYRICK & LOWER) AND HESPERILLA SARNIA ATKINS (LEPIDOPTERA: HESPERIIDAE)

摘要

Biological notes and distribution records are presented for three uncommon species of trapezitine skippers: Trapezites genevieveae Atkins, Signeta tymbophora (Meyrick & Lower) and Hesperilla sarnia Atkins. Between 2000 and 2007, a number of observations were made of three endemic trapezitine skippers in SE Queensland. Although the larval food plants of each species are local but fairly widespread within temperate and subtropical biomes in eastern Australia, the skippers are uncommon to rare with short flight seasons and are found only within limited areas. It appears that further, individually specific requirements, possibly climatic, altitude and microhabitat associations, are necessary to each species and thus are probable subjects of conservation value that emphasise the importance of the particular biomes that support them.
