third instar larval stage [FBdv_00005339]
The third larval instar begins at the second larval molt and ends at puparium formation. Anterior spiracles are open to the outside; posterior spiracles have three openings each, and four groups of large branched hairs. The salivary glands extend to the second abdominal segment, with cells larger in the posterior than in the anterior of the gland. Mouth hooks typically have 9-12 teeth. About 24 hours before pupariation (at 25 degree C), larvae stop feeding and climb away from their food. Duration at 25 degrees C: approximately 48 hours (72-120 hours after egg laying; 48-96 hours after hatching). Temporal ordering number - 430.
