Crossing of a thick vein specials

How does Lyonetia clerkella cross a major vein? Thick leaf veins form a obstacle for mining larvae. Often a gallery follows a vein for several centimeters, until the vein nears the leaf margin, where the vein becomes much thinner; then the vein is crossed by simply eating through it. When…
