The Citrus Fruitpiercer (Gonodonta nutrix) is so named for the adults habit of feeding on orange juice by piercing the skin of the mature fruit. Adults pierce the fruit by pressing the distal end of the straw-like proboscis against the fruit and oscillating the curved center portion of the proboscis to the right and left. The distal end of the mouth part has several triangular shaped protrusions which serve to cut holes through the orange rind. Needless to say, this is an economically important pest of orange crops in Florida. Adults have a wing span of up to 40 mm. Larvae feed on Annona species.
