Live adult vi
The attacks differ from the above ground forms only in their position with reference to the soil surface.
Some subterranean insects spend their entire life cycle below ground.
Regardless, insects with an incomplete life cycle are unique in that they hatch from eggs into tiny nymphs that resemble the adult stage.
They stay in the nymphal stage for several weeks, while growing and molting into larger insects until they reach adulthood.
Moths and butterflies also have a complete life cycle similar to beetles except that the damaging stage is the larvae or worm stage which usually feeds on the stems, leaves or fruits.
The hole made in this way is so small that it cannot be seen with the unaided eye, but the withdrawal of the sap results in either minute white, brown or red spotting on leaves, fruits and/or twigs; leaf curling; deformed fruit; or a general wilting, browning and dying of the entire plant.A large hole in a fruit, seed, nut, twig or trunk generally indicates where the insect has come out, and not the point where it entered.
