This weeks topic is Geometry and I offer a group of Lacewing eggs which are laid in a spiral. This is a fairly typical pattern for this insect. The egg is actually laid with a stalk supporting it above the surface that it is laid on. In this case, it was a mango on a tree in my yard.
If you look carefully, you can see that there are several little drops of some liquid on each of the stalks. This is something that is distasteful to ants and helps keep the eggs from being eaten. This shot doesn’t show the spiral as well but gives a better view of the stalks and liquid.
