It inhabits south-facing warm slopes and dry grasslands, at an elevation up to {{convert|2400|m}} above sea level.[3][5] DescriptionMegalodontes cephalotes can reach a length of {{convert|8|-|12|mm}}.[4] These rather rare sawflies have a black glossy body with narrow light yellow bands on the abdomen. Pronotum shows a yellow upper margin. The head is large, the antennae are pectinate, with darkened flabelli towards the apex. The wings are reddish.[3]BiologyAdults can be found from May to July, mainly on white and yellow inflorescences.[4] They feed on pollen, nectar and honeydew, while young larvae feed gregariously on a few flowering plants (Laserpitium, Seseli and Peucedanum species).[3][4][5] References{{Wikispecies}}{{Commons}}1. ^[https://fauna-eu.org/cdm_dataportal/taxon/68e67895-2d58-4082-9546-a0297a4af5b6 Fauna europaea] 2. ^[https://www.biolib.cz/en/taxon/id63056/ Biolib] 3. ^1 2 3 Taeger, A. 2002 [https://www.researchgate.net/publication/269994386_The_Megalodontesidae_of_Europe_Hymenoptera_Symphyta The Megalodontesidae of Europe (Hymenoptera, Symphyta).] In: Viitasaari, M.
