Animal Crossing: Last Chance To Catch These Bugs And Fish In New Horizons Before They Leave

TL;DR

  • Northern Hemisphere loses 22 fish, 16 bugs, and 7 sea creatures including valuable sharks and butterflies
  • Southern Hemisphere says goodbye to 6 fish, 1 bug, and 1 sea creature with premium species like stringfish
  • The gigas giant clam (15,000 bells) and emperor butterfly (4,000 bells) are top priority catches
  • Sharks and rare river fish require specific timing and location strategies
  • Complete your Critterpedia before October to avoid waiting months for returning species

As September draws to a close, Animal Crossing: New Horizons players face a critical deadline for completing their creature collections. The transition to October brings significant changes to available species across both hemispheres, with many valuable specimens preparing to depart your island.

Understanding these seasonal shifts is essential for maximizing your Critterpedia completion and bell earnings. This guide provides comprehensive coverage of all departing creatures along with expert strategies to ensure you don’t miss these limited-time opportunities.

Seasonal creature rotations follow real-world migration patterns, creating authentic ecological experiences. Missing these final September catches means waiting several months for their return, potentially delaying museum donations and profitable sales opportunities.

Northern Hemisphere islands experience the most dramatic creature turnover as summer species make way for autumn arrivals. The departure list includes 22 fish species, 16 different insects, and 7 marine creatures disappearing from October onward.

Premium Fish Exits: Shark varieties represent the most significant financial losses. Great white sharks (15,000 bells), hammerheads (8,000 bells), saw sharks (12,000 bells), and whale sharks (13,000 bells) all vanish after September. These ocean predators only appear during specific evening and nighttime hours, requiring strategic fishing sessions.

River and pond fish departing include the dorado (15,000 bells), arapaima (10,000 bells), and arowana (10,000 bells). These species share similar active periods from late afternoon through early morning, making coordinated catching efforts essential.

Insect Migration Patterns: Butterfly species dominate the insect departures, with the Queen Alexandra’s birdwing and agrias butterfly both valued at thousands of bells. Beetle enthusiasts should prioritize the goliath beetle (8,000 bells) and rainbow stag (6,000 bells), which remain active on trees during specific evening hours.

Sea Creature Strategy: The gigas giant clam stands out as the most valuable marine departure at 15,000 bells. Unlike fish, sea creatures require diving equipment and patience, as they’re often buried in sand or require chasing.

Southern Hemisphere players face fewer creature departures but shouldn’t underestimate their importance. The limited exits include premium-value species that represent significant bell-earning opportunities and critical museum donations.

Elusive River Fish: The stringfish (15,000 bells) and sturgeon (10,000 bells) are the standout departures. These species require specific river locations—the stringfish appears exclusively in clifftop rivers, while sturgeon spawn only at river mouths where freshwater meets the ocean.

Butterfly Priority: The emperor butterfly (4,000 bells) represents the sole insect departure. Its common appearance around flowers makes it an easy but valuable final catch opportunity.

Marine Finale: The red king crab (8,000 bells) is the only sea creature leaving Southern Hemisphere islands. Available all day in ocean waters, it offers flexible catching opportunities for busy players.

Southern Hemisphere transitions are generally less dramatic than Northern changes, but the high-value departing species make strategic catching essential for maximizing profits and collection completeness.

Time Management Mastery: Schedule your catching sessions around the most valuable creatures’ active hours. Evening sessions from 4 PM to 9 AM capture the majority of premium fish including all shark varieties and rare river species.

Location Optimization: Northern Hemisphere players should prioritize ocean fishing for sharks and river fishing for dorado/arapaima. Southern Hemisphere collectors need to focus on clifftop rivers for stringfish and river mouths for sturgeon.

Profit Maximization Techniques: Focus on creatures valued above 5,000 bells first. The gigas giant clam, great white shark, and stringfish all offer 15,000 bell returns, making them top financial priorities.

Common Mistakes to Avoid: Don’t waste time on common species when premium creatures are available. Avoid scaring away valuable bugs by approaching carefully and using the net from optimal angles.

Advanced Player Tips: Use fish bait to spawn specific creatures in desired locations. Clear your beaches of shells and create flower gardens in strategic locations to attract valuable butterflies.

Remember that completing your Critterpedia before seasonal transitions ensures you won’t face months-long waits for returning species. Strategic planning now saves significant time and effort later.

Action Checklist

  • Prioritize catching gigas giant clam, sharks, and premium butterflies before October
  • Schedule evening sessions (4 PM – 9 AM) for maximum valuable creature encounters
  • Visit specific locations: ocean for sharks, clifftop rivers for stringfish, river mouths for sturgeon
  • Create fish bait and prepare diving gear for targeted creature spawning
  • Donate missing species to museum first, then sell duplicates for profit
