You summon a giant centipede, spider, or wasp (chosen when you cast the spell). It manifests in an unoccupied space you can see within range and uses the Giant Insect stat block. The form you choose determines certain details in its stat block. The creature disappears when it drops to 0 Hit Points or when the spell ends.
The creature is an ally to you and your allies. In combat, the creature shares your Initiative count, but it takes its turn immediately after yours. It obeys your verbal commands (no action required by you). If you don't issue any, it takes the Dodge action and uses its movement to avoid danger.
Use the spell slot's level for the spell's level in the stat block.

Other Planes and Effects
Below is information about this spell as it relates to other planes and area of effects (i.e. underwater). Some of the information is pulled official D&D sources (such as books and the twitter feeds of D&D officials), but other information is derived from forums and online discussions. As always, it is up to the DM to decide how they wish to handle spell effects.
Summoning in Sigil
From Planescape Adventures in the Multiverse, Sigil and the Outlands, "With the exception of permanent teleportation circles, the Lady of Pain prevents spells and other powers from allowing anything to enter the City of Doors. That means creatures and objects from outside in the multiverse can't be summoned or conjured into Sigil by any means. Summoning abilities a character might have, such as the conjure elemental spell or a class feature that summons a companion, still function as normal with these features calling only creatures that exist somewhere within Sigil itself."
Underwater - Verbal Component
Official rules have been verified by Jeremy Crawford - "No rule prohibits verbal components from working underwater. Keep in mind that if you're talking, you're not holding your breath." Hence, while submerged underwater and holding its breath, a creature can cast a spell that requires a verbal component. After casting the spell, if the creature can't breathe underwater, it immediately runs out of breath. The creature can survive for a number of rounds equal to its Constitution modifier (minimum of 1 round).
