#Drosophila #Advent Day15: A new genus with Scaptomyza pallida, a widespread species that breeds as a generalist on decaying plants https://link.springer.com/content/pdf/10.1007/BF00317362.pdf . Sister to the overly flamboyant Hawaiian Drosophila (#Idiomyia), the genus #Scaptomyza either invaded #Hawaii twice or evolved there and escaped three times https://academic.oup.com/genetics/article/209/1/1/5930949 . It is easy to sweep-net pallida from herbs or compost, and while these individuals may not look very pallid, other ones are more so http://www.drosophila.jp/jdd/class/030706/03070609.pdf
