Abstract:
The intestines of insects are assumed to be the niche of various microbial groups, and a unique microflora could be formed under environmental conditions different from mammalian intestinal tracts. This chapter describes the bacterial flora formed in the intestines of two dragonfly species, "akatombo" (the red dragonfly; Sympetrum frequens) and "usubaki-tombo" (Pantala flavescens), which fly over a long distance, and carotenoid-producing microorganisms isolated from this flora. C30 carotenoids, which were produced by a bacterium Kurthia gibsonii isolated from S. frequens, were structurally determined.
