An interesting study of living things in the world around us involves how things move from one place to another. There are many creatures with muscles that move their legs or wings to travel from place-to-place. Other forms of life use spring-loaded movement with power greater than muscles can provide.
The larvae of the gall midge Asphondylia flip with power by using a built-in latch that acts as a spring. Gall midges lay their eggs on silverrod or goldenrod plants (Solidago). The midges grow from an egg to a larva inside a gall that grows on the plant. The larva’s body forms into an ellipse by meshing together the back and front using a velcro-like surface on each end. As the midge larva grows, the tension on the surfaces increases until it finally breaks free, shooting the midge as far as 36 times its body length. We previously reported on the so-called “Dracula ant” (Mystrium camillae) which has the world’s fastest jaws that operate on a mechanism which gives them spring-loaded movement.
Some plants like the Chinese Witch Hazel (Hamamelis mollis) have a similar structure in their fruit. As the fruit grows, it builds up stress until the edges of the fruit break, shooting the seed great distances. That spring-loaded launch method spreads the seeds over a wider area. Also, we previously reported on the sandbox tree (Hura crepitans) nicknamed “the dynamite tree.” Its seedpods open explosively by a spring-loaded movement that scatters the seeds.
These are all design features built into the very structure of the organisms to allow locomotion. Even the smallest creatures such as ants and midge flies and plants that are rooted in place use spring-loaded movement. Everywhere we look in the creation, we see God’s designs at work. His wonder-working hand has created a great diversity in all of life.
As Paul wrote in Romans 1:20, “For the invisible things of Him (His wisdom, power, and design) from the creation of the world are clearly seen, being understood by the things that are made even His eternal power and deity; so that mankind is without excuse…”

Insects are the most prolific of all animal groups on the planet. History records instances in which scourges of insects have caused massive destruction when they are not held in check. One of the most effective controllers of insect populations is other
