Cells with a segmented horseshoe-shaped nucleus are segmented nuclei are precursors of neutrophils called metamyelocytes.
Following 3 divisions, the myelocytes are transformed into metamyelocytes: the majority of protein synthesis ceases. They have a curved or elongated horseshoe or sausage core; dense chromatin. This elongated nucleus will undergo one to three pinches (strictures), to give birth to the nuclear lobes.
The fungus continues to grow in the ant body and finally comes out from the ants head and spread its spores. Therefore the type of nutrition is parasitic
