Giant bluebottle flies are normally nonaggressive unless bothered.

Disease (Ex): Filth fever – bite, Fortitude DC 12, incubation period 1d3 days, damage 1d3 Dexterity and 1d3 Constitution. The save DC is Constitution-based.

Resistant to Disease (Ex): A giant bluebottle fly has a +4 racial bonus on Fortitude saves vs. disease.

Wallcrawling (Ex): A giant bluebottle fly need not make Climb checks to traverse a vertical or horizontal surface (even upside down). It retains its Dexterity bonus to Armor Class while Climbing and opponents get no special bonus to their attacks against it.

Skills: Giant bluebottle flies have a +2 racial bonus on Listen and Spot checks and a +8 racial bonus on Climb checks. A giant bluebottle fly can always choose to take 10 on Climb checks, even if rushed or threatened. Giant bluebottle flies use either their Strength or Dexterity modifier for Climb checks, whichever is higher.
