Explanation of Names
Crudelis is Latin for "cruel".
Wingspan about 20-24 mm.
Larva to about 25 mm. (1)
Larva - whitish gray, sometimed with a purple tinge, pale and broken middorsal stripe, purple stripe just above the legs; head white, brown in front and black posteriorly. (1)
Adult - forewing light brownish-gray, usually with discernible AM, median, PM, and subterminal lines; small black patch just inside subterminal line at costa has notch in lower corner; PM line bulges slightly outward below reniform spot, then continues in wavy line to inner margin; reniform spot represented by pale irregular blotch; diffuse blackish shading overlies much of median line; dark shading in terminal area, sometimes with reddish tint; terminal line black, scalloped; fringe pale, checkered with dark scales at vein tips; hindwing with similar color and pattern as forewing.

Crumb reported the larval host as "catclaw (Acacia)." (1)

In other Toxonprucha species, either the forewing's black costal patch is outside the subterminal line, or the PM line is shaped very differently, touching the median line in the center of the wing.
