Description: A mostly pale species with some brown markings on the wing; there is a bold, dark brown "7"-shaped mark on the wings, and several small red marks on the outer edges. Notably, wing vein CuA is forked, dividing the wing cell into small cell C5 and larger cell C4 (besides C4, C3a is also large); in some other Anotia species, the forked vein and therefore C5 are absent. The abdomen has several dark brown segments, though in some individuals the abdomen is entirely pale, and the wing markings are less bold as well. In dark individuals, the thorax has a broad brown band across the base (with a white tip), and a broad brown median line. The antennal stubs are a light brown.

Habitats and Life History
Habitats: Has been found near mixed hardwood forest.
Plant Associates: Derbidae are known or assumed to feed on fungal hyphae as immatures (UDEL).
Behavior: Can be attracted at night with a light.
Comment: This species is most similar to A. burnetii. A. burnetii has the first three segments of the abdomen with a mid-dorsal stripe, A. robertsonii typically does not. Additionally, while both species have a similar wing pattern, this is [typically] much more bold in robertsonii (see pale specimens, above).

Pale specimens of A. robertsonii could be a result of general, sexual dimorphism (though pale individuals of opposite sexes have been documented mating with one another) or could be evidence of there being 2 species that have not been properly sorted out yet. (UDEL)
