Lake Huron Locust
A Great Lakes endemic grasshopper vanishes against pale dune sand until a short flight flashes color above the upper beach.

Lake Huron locust occurs only along portions of Lakes Huron, Michigan, and Superior, with most known sites in Michigan. It uses open, sparsely vegetated sand maintained by wind, waves, ice, and shifting dunes, feeding on dune plants and relying on bare patches for heat and movement.
Shoreline hardening, development, trampling, off-road vehicles, invasive plants, and vegetation succession can remove habitat by either destroying dunes or stabilizing them too completely. Responsible observation means staying on durable open sand where permitted and avoiding planted restoration zones.
- Range
- Great Lakes endemic
- Stronghold
- Michigan shoreline
- Strategy
- Extreme sand camouflage
Quick guide
- Best chance
- Walk open dune habitat on warm summer days
- Watch for
- Use the yellow hindwing flash to confirm flight
See the dune camouflage before the flash
- Wait for movement
- A flushed insect often flies only a short distance and disappears immediately when it lands.
- Check the hind wing
- Look for pale yellow on the spread hind wing, then use a photograph rather than repeated flushing.
- Compare the forewing
- Mottled gray-brown forewings should echo local sand and pebbles; several band-winged grasshoppers overlap.
- Protect open patches
- Use established beach access and never chase through marram planting, fenced dunes, or nesting-bird closures.
Good to know
The bare sand it needs is not degraded habitat by definition. Healthy Great Lakes dunes naturally include moving, sparsely vegetated patches, and restoring them does not mean planting every open surface.
