Yes, many of the insects we know today are descended from creatures that came into being even before the Mesozoic era (the age of the dinosaurs). Others arose in the Cretaceous period - the latter part of the Mesozoic. Among these were the eusocial bees, the type that live in colonies and make honey. The bees, along with other insects, developed together with the first angiosperms, or flowering plants.
