| how do "mute" cicadas produce their calling songs? | insects have evolved a variety of structures and mechanisms to produce sounds, which are used for communication both within and between species. among acoustic insects, cicada males are particularly known for their loud and diverse sounds which function importantly in communication. the main method of sound production in cicadas is the tymbal mechanism, and a relative small number of cicada species possess both tymbal and stridulatory organs. however, cicadas of the genus karenia do not have any ... | 2015 | 25714608 |
| gross morphology and ultrastructure of salivary glands of the mute cicada karenia caelatata distant (hemiptera: cicadoidea). | salivary glands of the cicada karenia caelatata distant were investigated using light microscopy and transmission electron microscopy. the salivary glands are paired structures and consist of principal glands and accessory glands. the principal gland is subdivided into anterior lobe and posterior lobe; the former contains about 34-39 long digitate lobules, while the latter contains approximately 30-33 long digitate lobules and 13-22 short digitate lobules. these short digitate lobules, about one ... | 2013 | 23245811 |
| sichuan snub-nosed monkeys (rhinopithecus roxellana) consume cicadas in the qinling mountains, china. | there is limited information on insectivory in folivorous primates. here, we report that wild sichuan snub-nosed monkeys (rhinopithecus roxellana) consume cicadas (karenia caelatata) in the qinling mountains of china. our research suggests that snub-nosed monkeys expand their diet and prey on cicadas during summer and early autumn, possibly in response to increased availability of these insects and their relatively high protein and fat content relative to leaves. | 2016 | 26938209 |
