Added strength is exemplified by the characteristic, complete sclerotisation of the intermediate sclerite and heavy sclerotisation of the vertical plate. Furthermore, in the tephritids, additional bracing occurs via smooth alignment between the intermediate and basal sclerites, similar to that of S. coleoptrata. However, the cornua in phytophages appear weak. There is abrupt termination of sclerotisation partway along the ventral cornu, and there are windows and areas lacking sclerotisation in the dorsal cornu. In phytophagous larvae, cibarial ridges are absent and, possibly as a consequence, the terminal valve is reduced. There is probably a trade off on the ventral cornu between the need to resist distortion via sclerotisation and the reduced need for sclerotisation resulting from the loss of cibarial ridges and terminal valve. This explains the characteristic pattern of sclerotisation in the ventral cornu. A factor explaining the pattern of sclerotisation in the dorsal cornu is probably space. The films reveal that, in live phytophagous larvae, the dorsal cornu bends along these windows. Bent over dorsal cornua reduce the height of the head skeleton. This may compensate for lack of space caused by up and down movement of the head skeleton and narrow, confined feeding places		1														https://treatment.plazi.org/id/03F4879DFFA350589232B6B8FC5D5F1D#3B353CD6FFB4505893AAB7BEFE4A5B41				MaterialCitation
