from 0.2 to 3.0 μm in diameter. In some, putative isometric virions are barely visible
as dark specks (Fig. 2.4). Extant cypoviruses infect the midgut of a wide range of
insects, including Ceratopogonidae, along with a variety of other lower Diptera
(Nematocera) (Poinar and Thomas 1984; Poinar and Poinar 2005).
Also in Myanmar amber is evidence of a nuclear polyhedrosis virus (NPV)
(Baculoviridae) infecting a sand fly (Diptera: Phlebotomidae) (Poinar and Poinar
2005) (Figs. 2.5 and 2.6). The inclusion bodies (polyhedra) are irregular and in
some, putative rod-shaped virions are barely visible as dark rods (Fig. 2.7). Nuclear
