What must an insect immediately do after shedding its old shell to expand the new, underlying structure?

Answer

Rapidly pump body fluid (hemolymph) into the new shell

Immediately following the shed, the insect must quickly push hemolymph into the newly formed cuticle to expand it to its maximum size before the chitin cross-links and hardens.
