Plate 10. Calcium oxalate crystals associated with the silk moth, Bombyx mori. 1. Section <strong>of</strong> the silkworm’s gut<br />
containing pieces <strong>of</strong> mulberry (Morus alba) leaves. Note various anatomical features <strong>of</strong> the leaf that are still well<br />
preserved, including a cystolith. 2. Single piece <strong>of</strong> mulberry leaf in the caterpillar’s gut showing druses <strong>of</strong> calcium<br />
oxalate under polarized light. 3. Isolated crystals from the silkworms’ Malpigian tubules viewed under polarized<br />
light. 4. A fractured Malpigian tubule cell with attached CaOx twin crystals. 5. Twin crystals <strong>of</strong> CaOx produced<br />
on the surface <strong>of</strong> the Malpigian tubule. 6. Twin crystals <strong>of</strong> CaOx associated with a lawn <strong>of</strong> elongate microvilli. 7.<br />
Side view <strong>of</strong> two twin crystals <strong>of</strong> CaOx produced in the Malpigian tubules.<br />
