of Thyreus on the island. In the males, the distance between the two eyes is 1.8mm at the top of the eyes and 1.3mm at the bottom. In the females, the distance between the eyes is about 1.9mm at the top and 1.3mm at the bottom. Both sexes are covered in black or dark brownish-grey pubescence (short hairs) over most of the body. However, parts of the face, legs, and the mesosoma (the middle section of the body) are covered with white, feathery hairs instead. Breeding and parasitism The primary hosts of T. denolii and the other three members of Thyreus in Cape Verde are bees in the genus Amegilla, with which it is commonly associated in the field. If the various populations of T. denolli across the islands are indeed separate species, then it is parasitic on three separate species of Amagilla. Being a member of Melectini, T. denolii is a kleptoparasitic insect. The females of this tribe lay their eggs in the nest of their host, and their larvae use the resources and stored food provided by the host, at the expense of the host's young.
