◆ St_Develop()

TTypesOfBeetleState Ladybird_Larvae1::St_Develop ( )

overrideprotectedvirtual

The main behaviour method that is responsible for the development and eventually leading to larvae2.

Function that controls daily development, in addition controls feeding and movement. Larva only moves if there is not enough aphids or lower larvae to feed upon If it reaches the maximum daily distance and haven't got enough food– it dies.

Reimplemented from Beetle_Larvae.
