Theobroma cacao as culinary, purposes. Some mixtures included maize, chili, vanilla ("Vanilla planifolia"), and honey. Archaeological evidence for use of cacao, while relatively sparse, has come from the recovery of whole cacao beans at Uaxactun, Guatemala and from the preservation of wood fragments of the cacao tree at Belize sites including Cuello and Pulltrouser Swamp. In addition, analysis of residues from ceramic vessels has found traces of theobromine and caffeine in early formative vessels from Puerto Escondido, Honduras (1100–900 BC) and in middle formative vessels from Colha, Belize (600–400 BC) using similar techniques to those used to extract chocolate residues from four
Midge greatly from species to species, though within any particular family, midges commonly have similar ecological roles. One type of midge "ceratopogonid midges" (a type of fly in the family Dipteran) is a major pollinator of "Theobroma cacao" (cocoa tree) because of its unique morphological and behavioral characteristics. Having natural pollinators has beneficial effects in both agricultural and biological production because it increases "Theobroma cacao" crop yield and also density of predators of the midges (still beneficial to all parties). Examples of families that include species of midges include: The Ceratopogonidae (biting midges) include serious blood-sucking pests, feeding both on humans
