Triozidae species have the three main veins in the forewing arising from a common point, and have usually pointed forewings with radular spinules. Many cannot be separated without dissection, but host-plants can be useful.
T. vitreoradiata is typically glue-green in young adults, but parts of the dorsal surface darken to give black transverse abdominal bands, and darker regions on the head and fore-body; intervening areas may become red-brown. The outer vein of the forewing is unusually sinuous. The nymphs produce a conspicuous corona of radiating waxy filaments, giveing the species its name.
This species has been established in the UK since 1993, and is now known widely across southern England, and in the Midland Valley Scotland. It feeds on various species of Pittosporum.
