Plain Schizura
Schizura apicalis (Grote and Robinson, 1866)
Insects

Identifying Characteristics [-]
Plain Schizura has a wingspan of 2.6 to 3.2 cm. The forewing is gray with brown-shading at the base and anal angle. Indistinct, blackish lines are present on the forewing as well. The hind wing is off-white. The males have a black patch at the anal angle while the female has a "blackish" patch (Covell 1984). This species is similar to chestnut Schizura. Contrasting to the plain Schizura, the chestnut Schizura has a strikingly black thorax and the hindwing is dark brownish (Beadle and Leckie 2012). The forewing is gray with brown shading on the plain Schizura and gray with red shading and whitish on the apex for the chestnut. They both have a black reniform spot which is crescent-shaped on plain Schizura and can be crescent-shaped or shaped as a vertical dash on the chestnut Schizura. With the chestnut though, the spot joins with a blackish triangle, widening toward the outer margin (Covell 1984). They are similar in size, as chestnut has a wingspan of 3 to 3.5 cm.
