PUPA

• The third stage larvae spins a cocoon around its body
• The cocoon is sticky and so becomes covered with dust and debris- camouflaged
• Remain quiescent till the arrival of the host
• The pupa emerges from the cocoon in response to the bark of the dog or the footfall of the host
• Usually the pupa is ready to moult by 1-3 weeks
