Akko dionaea Birdsong and Robins is reported here from the Colombian Caribbean, based on specimens collected at the mouth of the estuary Ciénaga Grande de Santa Marta. Ten night collections with channel nets at the mouth of the estuary yielded a total of 228 specimens representing larval to juvenile stages. Specimens were captured during the new and full moon, mainly during the dry season. Larval and juvenile stages of A. dionaea are described here for the first time. The species  undergoes strong allometric changes during its development, mainly in the  length of the head and eye. The species is described and the ecology and biogeography of the species are discussed.
