Abstract The last past two decades, there has been a tremendous expansion in the discovery and description of novel insect- specific viruses (ISVs). This has corresponded with progresses in metagenomic analyses for virus revealing and the increasing attention in insect microbiomes. Plentiful of the new ISVs seem to be members of the family Flaviviridae, genus Flavivirus, and are usual in insect populations in wildlife, with a global geographic circulation.
