We have ants running around on the deck that are about the same size as these icing ones. That's why it would have been especially disturbing if I'd used them to decorate the cupcakes I brought to a potluck today. They're about the easiest thing you can imagine to pipe, but the problem is they're extremely fragile; one of the six I piped broke in half and lost its legs when I was setting them up for the final photo. The best way to pipe these critters might be to do the bodies and antennae first, then place them on your cupcake or whatever, then pipe the legs. Anyway, all you'll need are round #5 and #1 tips, stiff consistency black royal icing (I used Super Black Soft Gel Paste by AmeriColor), parchment paper squares, and a dusting pouch filled with a 50/50 mix of powdered sugar and cornstarch. Start by piping the head, which is basically a teardrop. Hold the #5 tip against the surface at a 45 degree angle, squeeze out a ball, and pull the tip away so a peak remains.
