This was shot at 210mm, 1/200 sec., f/5 and ISO 400. At the Beercan's minimum focus distance, the depth of field is less than 10mm. That would mean that, while one wing of a butterfly would be in focus, the other wing would not, one antenna would be in focus while the other would not. That seems to be what happened here.

You could have stopped down a little to get a larger depth of field (about 30mm at f/8 )and that would have solved the problem.
