It is possible that the male Altaroth and/or the Queen have wings while the workers that are females have none similar to real ants. But as no canon information about this is revealed, it's just a speculation.

Also, not all insects have wings. Look at Millipedes and Centipedes. They have no wings but also are very primitive insects that got seperated from another line which evolved wings, that's why I think Kunchuu is also a pretty primitive insect that is on a evolutionary path that is seperated from the Neopterons with wings that evolved after the seperation.
