Possibly, but M. serricauda is a leafcutter. Leafcutters usually don't fold their wings over the body when they alight and if it is a female the abdomen should be leaf shaped not cylindrical. If it is a male we might hope to see the 'curled leaf' structure on the foreleg. Because of all these things that I did not see, I chose not to guess that it might be M. serricauda, but it certainly could be.
