Lord Howe Island’s removal of invasive rodents has led to a rebound in native invertebrate life, according to researchers and local naturalists. Rodents such as rats and mice were introduced more than a century ago and significantly reduced native plants and animals across the island. With rodents removed, native insects and other invertebrates are increasing again, contributing to ecosystem recovery. Sources describe a renewed presence of native insects, including cockroaches, as well as other invertebrates such as stag beetles. Observers report that during warmer months, species like the island’s stag beetle are more visible as they fly in search of mates. The developments are presented as positive signs for the island’s broader ecological balance following rodent control and eradication efforts tied to conservation outcomes. Overall, the reporting emphasizes that restoring invertebrate populations can support the functioning of the island’s food webs and habitats, reflecting gradual recovery after long-term rodent impacts.
Invertebrate populations rebound on Lord Howe Island after invasive rodent removal

- Invasive rats and mice were introduced to Lord Howe Island more than a century ago and harmed native wildlife.
- Rodent removal efforts are followed by a rebound in native invertebrate populations.
- Reports cite increases in insects including native cockroaches and other insects.
- Warmer months bring sightings of the island’s native stag beetle as part of the recovery.
- The rebound is described as relevant to the island’s wider ecosystem health.
Rodents arrived on the subtropical island more than a century ago, decimating its native flora and fauna – but its invertebrates are once again boomingIn the summer months, Lord Howe Island’s unique stag beetle, with wing cases that appear forged from iridescent green metal, fly around the ancient tree tops looking for a mate.“That’s really something wonderful,” said Ian Hutton, a naturalist and nature guide on the World Heritage-listed island.
