Mealy bugs are sexually dimorphic which means that the male and the female species are way different beyond the differences in their sexual organs.

Female mealy bugs feed on plant sap as well as the roots of the plant and the bottom of the fruit. They attach themselves to the succulent and secrete a powdery wax layer which acts as a protection shield while they are sucking the plant juices.

Unlike female mealy bugs adult male mealy bugs don’t feed themselves and they have a very short span of life. The major responsibility of male mealy bugs is to fertilize the female mealy bugs. 

What causes mealy bugs on succulents?

Mealy bugs are parasites which are more likely to grow in moist and warm climate but there two main reasons which are actions of human activities that are likely to cause mealy bugs.

But over fertilizing can be very harmful because it makes the soil extra warm and moist which is the best way to mealy bugs to the roots.
