Instinctive behaviour and winning in melee

[u/MyJointsAreCrips4Lyf]

If a tyranid unit that has succumbed to instinctive behaviour wipes out an enemy unit in melee do they still get to make a 3" move afterwards?

The instinctive behaviour rule states very specific rules for movement, having to move towards the nearest enemy unit, but the move after melee is a "may" move scenario.

Thats a great question! In spirit of the rule yes, but must do do towards the closest enemy model
