Four major types of limestone formations (speleothems): Dripstones: Straws are thin walled hollow formations that resemble drinking straws. As water drips slowly from the roof of the cave, it deposits a microscopic ring of calcite crystal. These rings continue to build and can form straws many centimetres long.
If the sample has more than two or three grubs, you should probably take steps to reduce grub damage. Because grubs sometimes damage only parts of a lawn, take more than one sample if the lawn is damaged in patches.It might not be necessary to treat the entire lawn.t may even become possible to roll the turf up as if it were carpet. You should also control grubs if you notice other animals, such as crows, raccoons or skunks, digging up grubs in the yard and causing damage. In temperate climates, grub damage will be most pronounced during late summer and fall.
