The Eye of the Fly

This eye was surgically removed from a fly that up and died on the window sill of our classroom. A fly has a Compound Eye, very different from our own. Study this eye using LOW, MEDIUM and HIGH powers.

32. In MEDIUM power, focus through the

various layers until you see many small cell- shaped structures. Each cell or segment can “see” its own separate image. DRAW a portion of what you see. 33. On HIGH power, adjust the focus and lighting until you get a good view of one individual segment. DRAW a single segment of the compound eye in detail.
