"workers were recorded as they regurgitated to larvae 1.5-3.0 in total length or fed tufts of hyphae to larvae in this size range (data accumulated during two days). Feeding large-intermediate larvae: workers were recorded as they regurgitated to larvae 3.0-5.0 mm in total length or fed tufts of
hyphae to larvae in this size range (data from five days). Feeding largest larvae: workers were recorded as they regurgitated to larvae greater than 5.0 mm or fed tufts of hyphae to larvae in the same size range (data from two days)."

"It is possible that the adult gardener ants regurgitate chitinases from the labial glands onto the fungal material fed to the larvae, initiating the digestion of the fungal cell walls even prior to ingestion by the larvae. Conversely, larvae could regurgitate their own labial gland secretions to
supplement the digestive needs of the adults that live in close association with the larvae, receiving these liquids by
Dort wird übrigens auch nochmal auf Delange eingegangen:
"In the case of Messor capitatus, studies have shown that the larvae supply proteinases to the adults, whilst in exchange, the adults supply carbohydrases to the larvae (Delage, 1968)."
