Crickets, including British bush-crickets, tend to have long antennae; grasshoppers have shorter antennae. Both jump, and colour alone is an unreliable guide.
The difference at a glance
Start with the antennae: crickets, including bush-crickets, tend to have long feelers, while grasshoppers have shorter ones. Both have powerful hind legs for jumping. In a British garden, “green means grasshopper” is an unreliable shortcut; some crickets are green and grasshopper colours vary. [1] [2]
| Feature | Cricket / bush-cricket | Grasshopper |
|---|---|---|
| Antennae | Typically long; often extend beyond the body. [1] | Shorter antennae. [1] [2] |
| Usual singing mechanism | Wings rubbed together. [1] | Hind legs rubbed against wings. [1] |
| Sound detection | Hearing organs on the front legs. [1] | Hearing organs near the base of the abdomen. [1] |
| Activity clue | Many active towards dusk; daytime exceptions exist. [1] | Often conspicuous on warm days. [2] |
| Colour | Can be green or brown; not a decisive test. [1] | Can vary even within one species. [2] |
| Shared point: jumping | Enlarged hind legs. [1] | Enlarged hind legs. [1] |
Imagine two photographs from a British garden. In the first, the feelers extend well beyond a brown insect’s body. That supports the cricket or bush-cricket side of the comparison. It does not tell you the species. In the second, a green insect has visibly short antennae: grasshopper is the better starting point. [1] [2]
Now crop the antennae out of both photographs. The useful distinction has disappeared. Describing the first as brown and the second as green does not recover the missing evidence. For a useful identification photograph, keep the head, entire antennae, body and hind legs in view.
A familiar chirp is produced by rubbing body parts, but the parts differ between the groups. These are typical mechanisms, not a promise that every insect will be calling when you find it. One British bush-cricket attracts a mate by drumming on a leaf rather than making the familiar wing song. [1]
Time of day is also a supporting clue. Some true crickets are daytime insects, so seeing one in sunshine does not turn it into a grasshopper. At species level, the song and the shape of the pronotum—the area immediately behind the head—can be more useful than overall colour. [1] [2]
If the key feature is hidden, record that uncertainty rather than guessing from colour.
No. Long antennae support the cricket/bush-cricket side. Colour does not override that clue, and a species name still needs more evidence. [1] [2]
No. Enlarged jumping hind legs are a shared feature. Look for the antennae and supporting details. [1]
No. Silence at one moment is not an identification feature, and activity patterns have exceptions. [1]
No. Bush-crickets belong on the long-antenna side of this comparison. A green body is not enough to distinguish them from grasshoppers. [1] [2]
