se tekst i artikkel

Acolastus er en slekt av biller som tilhører familiegruppen bladbiller (Chrysomelidae). Både larvene og de voksne (imago) er planteetere.

Utseende 
Små, sylindriske bladbiller, mer eller indre lyst brunlige. Kroppen er butt både foran og bak. Pronotum har en mørk, V-formet tegning. Det siste leddet av bakkroppen er synlig bak dekkvingene. Dekkvingene har dype furer. Antennene er ganske tynne og forholdsvis lange, gjerne lengre enn kroppen hos hannene. Beina er forholdsvis lange og kraftige.

Levevis 
Hettebladbiller er særlig aktive i varme og solskinn. De voksne besøker også blomster for å ete pollen.

Utbredelse 
Slekten er vidt utbredt i Afrika og Asia, mangler i Europa.
