The crimson worm is specifically adapted to living in the Middle East, particularly in Israel. Scientifically, the crimson worm is an insect rather than a worm. It has a hard shell with six legs, is roughly the size of the eraser on the head of a pencil (0.3 inches), and looks like a grub worm. But the most unusual thing about the crimson worm is its unique life cycle. Keep reading and you will understand why.
In ancient times, the dried bodies of the crimson worm were ground up and used to make scarlet dye. The dye was used to color clothing, particularly the robes of the high priest and the coverings of the tabernacle. The dye was vivid and permanent, making it highly valuable in Biblical times.
The female reproduces only once. When she is ready to lay her eggs, she climbs a tree, usually an oak, and permanently attaches herself to it. Her body then forms a hard, crimson shell that will protect her eggs. Once the larvae hatch inside this protective shell, they feed on their mother’s body for three days. During these three days, the mother secretes a crimson fluid that covers her body and the eggs, leaving a permanent stain on the tree. On the fourth day, the remainder of the mother’s body transforms into a white, heart-shaped wax, which then flakes off.
The red fluid produced by the worm and the transformation of the mother’s body to white wax are often linked to the Bible imagery of our scarlet sins made white as snow, emphasizing purification and redemption. The Hebrew word tola’ath used in the Scriptures, specifically refers to the crimson worm.
Often cited as a symbol of sacrifice, it was accepted as a foreshadow of Christ’s death on the cross. As the mother worm gives up her life to protect and nourish her babies, so Jesus offered Himself on the cross to protect and preserve mankind.
“ ‘Come now, and let us reason together,’ says the Lord, ‘though your sins are like scarlet, they shall be as white as snow; though they are red like crimson, they shall be as wool.’ ” Isaiah 1:18
