Acrosphacelus is a term that refers to a type of parasitic wasp. Its spelling can be difficult to comprehend at first glance, but understanding its IPA phonetic transcription can make it easier to spell. The word is pronounced "əˈkrɒsfəsələs", with the stress on the second syllable. The prefix "Acro-" means "top" or "highest", while "sphacelus" pertains to dead tissue. Hence, "acrosphacelus" translates to "parasitic wasp that feeds on dead tissue found on the upper part of a plant".
