This got me curious. At a quick search, I found out that there in fact is at least a species of flying insect larger than (the smallest) hummingbird:

The insect grows up to 7 cm in length whereas the bird can stay less than 6 cm at adulthood. No information about the insect weight though (for a proper comparison).
