“And they shall be Mine, saith the Lord of hosts, in that day when I
make up MY JEWELS.”
(Malachi 3:17)

To my dear Grandchildren

The Lacewing Fly

“The glory of the Lord shall endure forever: 
the Lord shall rejoice in His works.”
(Psalm 104:31)

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.  Then, before this spot of glue 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 top of each stalk, spacing them far enough apart so they will not eat each other when they hatch, because 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 12-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 an 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 eats away, 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.  This 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 Saviour.  In addition, He has given us hearts and minds capable of receiving this loving Saviour, 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” (Romans 6:23).

Have you accepted this wonderful gift?

Love you all - Grandpa
