I think it could be good if we got more information about how it works, but it can be dissatisfying to have that dropped on us suddenly. We can assume that the individual bugs are also super powered monster bugs, at least relative to other bugs.
If they're very fast and strong bugs, they could, for instance, break off, set up a tea set using smaller groups, and then rejoin the main body.
Edit: I tried to look up what the strongest insect is. It appears to be the dung beetle, able to lift about 2/3 of an ounce or .04 pounds:

I think we can grant that a monster bug is at least this strong, even if it lacks the size and exoskeleton of the dung beetle. It is, after all, no ordinary bug. 100 monster bugs therefore can lift 4 pounds, enabling them to comfortably carry a filled teacup.
Meanwhile, the tiger beetle can run 5.6 mph:

I will suggest a monster bug can move at least this fast, regardless of its appearance. The monster bug will also need no time needed to accelerate or decelerate, ie, it can immediately go from stationary to 5.6mph and then immediately go back to stationary.
Therefore 1000 monster bugs can instantly prepare a tea set while appearing to teleport and shape shift.
