Bees, ants, wasps and so forth are the Order Hymenoptera (membrane wings).
Flies are in the Order Diptera (two wings).
Here, we have several species of solitary bees. They are about the same size, but gray not orange abdomens, which are the introduced honey bee of commerce.
Far and away larger are our native bumble bees which live in small social colonies. Adult queens can be 4cm in length = they are huge things. Workers 3cm or less.
Those are black and yellow. My insect ID book identifies them as Megabombus pennsylvanicus.
There are smaller species of what we also call bumble bees, these are yellow, black and very distinctly bright orange abdomens.
The book is silent on the proper name but I could find it elsewhere.
