The intervein territory of mutant wings are partially transformed to vein tissue.
Wings form tubes, formed exclusively of vein cells.
Wings are blistered and ballooned and have small cells. Ballooned wings are typically composed entirely of small vein-like cells except for a strip at the center of the wing corresponding to the intervein region between L3 and L4.
