Some of the insects commonly infected by iflaviruses include aphids, leafhoppers, flies, bees, ants, silkworms and wasps.

The name "Ifla" is derived from the name "Infectious flacherie virus", a member species.

[2][1][3] Members of this family are insect-infecting viruses that consist of positive single-strand RNA genomes translated into a single polyprotein of ~3000 amino acids long.

It encodes helicase, protease and RNA-dependent RNA polymerase enzymes and four structural proteins (VP1–4).

The non-enveloped capsid has an icosahedral T=pseudo3 symmetry and is around 30 nm in diameter.
