The waste product of insects is?

The waste product of insects is typically excreted in the form of uric acid. Unlike other insects and mammals, insects do not have a separate organ for the elimination of liquid waste, like a bladder. Instead, they excrete nitrogenous waste in the form of uric acid, which is a solid substance. This solid form of waste helps to conserve water, as insects can lose a significant amount of water through evaporation. The uric acid is excreted through specialized structures called Malpighian tubules, which are found in the insect's abdomen. The uric acid is then passed out of the body through the anus.
