The Defiler is a relatively high-level Zerg creature. It requires plenty of research to bring it up to attack standards. However, once it's up to stuff it can provide some very helpful abailities for your swarm.
As can many Zerg units, the Defiler can burrow. There are two main reasons to do so:
In either case, burrowing requires that you monitor your units frequently, keeping an eye out for an opportune time to pop back to the surface.
The Dark Swarm ability is somewhat like Terran Science vessels' Irradiate ability. It can cover a fairly large area with putrid gases and damaging spores. One effective way to use the Plague is to send a couple of Zerglings toward an enemy base; when a bunch of enemies come out to fight, launch the Plague at them. It may not kill them, but biological creatures will sustain significant damage.
The Defilers' other ability is that of eating a fellow Zerg using the Consume command. This seems a little stomach-turning, but a Zergling is a small price to pay for a much-needed boost in energy for a Dark Swarm or a Plague. It might even be a good idea to group a couple of Zerglings with the Defilers so they'll have something to consume when their energy gets low.

Defilers are the perfect example of the fanatic and sadistic nature of the Zerg. Like the Larvae, the Defiler carries within it the genetic code of every other Zerg breed, but it does not produce them. To the contrary, the Defiler uses these genetic martices to produce cancer-like toxins which has dramatic and deadly effects. The Defiler prefers to avoid direct combat, relishing instead in the use of its unique bio-chemical abilities.
Defilers can also burrow into the ground like their lesser brethren. A common tactic of these vile creatures is to attack until they runout of prepared toxins, and then burrow down until they can rejuvenate their stores of venom.
The body of a Defiler is covered with a countless number of smaller creatures that feed off each other. By spontaneously launching a number of these creatures into the fray, the Defiler can create a thick cloud of living insects to distract the Swarm's enemies and provide cover for other Breeds.
With this ability, the Defiler produces a batch of corrosive spores that it then exposively projects in a dense cloud around its enemies. This highly toxin cloud corrodes anything caught within its midst.
As the only breed in the Swarm to show tendencies of cannibalism, the Defiler sometimes feeds off of its own species to regain lost energy. While this practice is particulary repulsive to most civilized species in the galaxy, it has proven to be an effective, if unsavory tactic.
