Only about one-half inch long, the lacewing is a pretty little fly with transparent wings in pale shades of green. It is a real friend to farmers.
When laying eggs, the female first deposits a spot of "glue" on a branch or stem of a bush. Before this hardens, she flips her tail upward, producing a long, thread-like stalk. The stalk quickly becomes tough and hard, and she repeats this process time after time. Then she places an egg on the end of each stalk, spacing them far enough apart so they will not eat each other when they hatch, since they are vicious, hungry little larvae.
In about a week, the larva appears. Cutting its way out of the egg, it slides down the smooth stalk, using its tail as a brake. The mother fly has arranged her nest of eggs close to where aphids are feeding on a plant. These aphids become food for the larva for about two weeks; then it is ready for a change. Attaching itself to the underside of a leaf, it spins a thread of white silk, wrapping itself in a cocoon where it will undergo a twelve-day change.
While in the cocoon, the larva develops specially designed cutting jaws. Using these, it slices around the top of its cocoon, leaving a small section as a hinge and anchor post. Pushing the lid open, it crawls out and spins another thread on which it dangles from the anchor. Soon its veins fill with blood, the wings dry, and it has become a full-grown lacewing fly. Now it returns to what it does best—eating aphids for the rest of its life. As it does this, it becomes a friend to farmers by helping protect their crops from these harmful pests.
It is interesting to see how the mother lacewing makes such careful preparations for her young: first by making the eggs look like part of a plant, and then by placing them where they will immediately find food when they come out of the eggs. It is another example of how God has given instincts to His creatures so they may fill their part in His total plan of creation.
God's ways with you and me are far more important than with these insects. He has given us a conscience to remind us that we are sinners and need a Savior. In addition, He has given us hearts and minds capable of receiving this loving Savior, and it is through Him and His death on the cross that we can enter heaven. He tells us, "The wages of sin is death; but the gift of God is eternal life through Jesus Christ our Lord" (Rom. 6:23). Have you accepted this wonderful gift?
