Summary
Development of flagella was investigated by transmission electron microscopy in spermatocytes and spermatids of the Mediterranean mealmoth, Ephestia kuehniella Z. Growing flagella displayed voluminous distal swellings. In short flagella the apical portion of the swellings contained an amorphous, dense accumulation. In more developed flagella a less dense proximal extension of the apical accumulation was formed, which in turn was in contact with the elongating flagellar microtubules. The material of the flagellar tip is interpreted as being a precursor of the axoneme containing mainly tubulin. The material may be converted into the axoneme.
