Combining with an adipokinetic hormone to initiate a change in cell activity. Adipokinetic hormones (AKHs) are protein or peptide hormones that are important for sugar and fat homeostasis in metazoa. In insects, they mobilize sugar and lipids from the insect fat body during energy-requiring activities such as flight and locomotion. They also contribute to hemolymph sugar homeostasis.
