As the 'froth' has a high concentration of air, thus providing insulation between the hot liquid and cooler air above the 'froth'.
It decreases the ability of coffee to retain heat for long
The best coffee to stay awake is one that is high in caffeine content, such as espresso or dark roast coffee.
They stay in their burrows at night and for the hotter part of the day.
No. It gets hotter - that is not the same

Coffee can stay hot in a carafe for about 1-2 hours, depending on the quality of the carafe and how well it retains heat.
it helps you stay awake longer
Actually coffee does not stay hotter in a ceramic cup vs a Styrofoam cup, but would stay hotter in a ceramic cup vs a paper cup.A good insulator for a water based liquid will reduce conduction and convection. Styrofoam works well keeping coffee warm because it has a small mass and a large volume. The small mass helps eliminate conduction. The large volume is because the sintering process traps tiny pockets of air that help eliminate convection. With those two together you get hot coffee longer.
People drank coffee to stay awake and to give them a boost in energy.
