About the size of a hawk, the giant fly is exactly that: a larger version of the flies you commonly see buzzing about carrion, picnics, garbage, and other food sources. Female giant flies, once mated, lay about 200 eggs in decaying organic matter. The eggs transition to larvae within 5-12 hours. (Wiggling maggots are actually those maggots that have gone through the third molting phase of the larval stage.) Those maggots that aren't acting as familiars then pupate for about 3 days before the adult form, the fly, emerges from the puparium. If a maggot is serving as a familiar, the maggot enters the pupa phase very briefly and immediately changes into its adult form. Giant flies eat various forms of decaying organic matter by ingesting then regurgitating it.

Combat

A giant fly uses its bite attack to nip at foes, then it flies away as quickly as possible before swooping in again for another bite. Wiggling maggots have no form of attack, but they possess vermin traits.

Vermin Traits: A giant fly or wiggling maggot is immune to all mind-affecting effects (charms, compulsions, phantasms, patterns, and morale effects). It also has darkvision (60-foot range).

Skills: Wiggling maggots receive a +4 racial bonus on Hide checks. Both giant flies and wiggling maggots use their Dexterity modifiers instead of their Strength modifiers for Climb checks.
