Tau emperor — size comparison — facts and sources

The tau emperor is orange-brown with four large eyespots. It inhabits deciduous forests, especially warm beechwoods where caterpillars develop.

Males may fly rapidly by day seeking females. Females are less mobile and chiefly crepuscular. Sexes also differ in size and antennae.

Adults do not feed. Caterpillars eat beech and other hosts; pupae overwinter.
