From: Evolution and phylogeny of insect endogenous retroviruses
Unrooted phylogenetic trees based on Gag motifs I to III (A), RT and RNaseH (B), and Env motif II (C) domains. Insect Metaviridae devoid of env-like genes appear in white lettering on gray background. These sequences (accession numbers) are: from Drosophila melanogaster, 412 (X04132) and burdock (U89994); Ulysses (Z24451) from D. virilis; micropia (XI 3304) from D. hydei; Woot (U09586) from Trilobium castaneum. Bootstrap values (when higher than 70%) and the divergence scales are indicated.
