Microcolona crypsicasis is a moth in the family Elachistidae. It was described by Edward Meyrick in 1897. It is found in Australia, where it has been recorded from New South Wales and Tasmania.[1]
The wingspan is 7–10 mm. The forewings are whitish ochreous, irrorated (sprinkled) with fuscous. There is a raised black dot on the fold at one-sixth and another beneath the fold at one-third. A third is found in the disc slightly above the middle and a fourth beneath the fold obliquely beyond the third, almost dorsal, and two transversely placed close together above the tornus. There is a cloudy fuscous spot on the costa before two-thirds and two black dots longitudinally placed at the apex. The hindwings are grey.[2]
