Chorthippus albomarginatus, the lesser marsh grasshopper, is a common grasshopper of European grassland both damp-marshy and (despite its name) dry, including salt-marsh and coastal habitats.
Distribution
[edit]The range of the lesser marsh grasshopper extends from Finland and southern Scandinavia in the north to Spain and Italy in the south.[1] It was once present only in the southern parts of the UK but has been expanding its range northwards.
Physical appearance
[edit]Females grow to approximately 20 millimetres (0.8 in) and are larger than males that grow to approximately 15 mm (0.6 in). The female almost always has a longitudinal white stripe on the wing whereas the male rarely does.
The region behind the head is referred to as the "pronotal side-keels" and the bars are approximately parallel in this species. Although quite similar, it can be distinguished from the meadow grasshopper Chorthippus parallelus, which also has straight pronotal side-keels, by a number of characteristics. These include its ability to fly, white stripe on female's wing, and more pointed snout. It often tends to be less brightly coloured and more straw-brown than Chorthippus parallelus.
Both sexes can be extremely variable in colour from green to brown.
Song and reproduction
[edit]The song is very similar to Chorthippus brunneus, though perhaps a little slower, with 2–6 chirps each lasting approximately half a second.[2] There can be an 'alternation song' between competing males. Females lay eggs at the base of grass blades.[3]
Development
[edit]More rapid development of C. albomarginatus (maturation at a younger age) was found to be associated with higher DNA damage.[4] The association of increased DNA damage with shorter developmental times suggests that there is a trade-off between genetic integrity and growth rate. Although rapid growth would likely provide a fitness advantage, the increase production of reactive oxygen species associated with rapid development would probably make the individual more subject to oxidative DNA damage with negative consequences later in life.[4]
