Description
Although there is some variation among the different species, all are flightless and quite large as grasshoppers go, with females attaining greater length at maturity than males. Distinctively colored and patterned, the immature ones have different coloration from their adult counterparts.
Life Cycle
After mating, lubbers deposit caches of approximately 25 to 50 eggs, depending on the species, in the ground during the summer. These eggs overwinter underground and begin to hatch out from mid-March to June, depending on the region.
Habitat and Feeding
Although each type of lubber has its preferred plant or plants on which it feeds in its natural environment, all are fairly catholic eaters and, given the opportunity, will usually cause damage to a wide variety of greenery. This includes one’s prized orchids.
Defensive Characteristics
Lubbers have at their disposal a variety of relatively unpalatable means of defending themselves against threats from other creatures. The bright coloration and patterning on a lubber’s shell is an aposematic, or warning, pattern to predators that they are unpalatable to downright poisonous.
Controls
Chemical control is effective only against the nymph stage. There are several insecticides toxic to grasshoppers that are registered for use on ornamentals, fruits and vegetables, such as Cygon. These are not, however, approved for use on orchids.
Overview
Phylogeny
Grasshoppers belong to the suborder Caelifera. Although "grasshopper" is sometimes used as a common name for the suborder in general, some sources restrict it to the more "advanced" groups. They may be placed in the infraorder Acrididea and have been referred-to as "short-horned grasshoppers" in older texts to distinguish them from the also-obsolete term "long-horned grasshopp…
Characteristics
Grasshoppers have the typical insect body plan of head, thorax and abdomen. The head is held vertically at an angle to the body, with the mouth at the bottom. The head bears a large pair of compound eyes which give all-round vision, three simple eyes which can detect light and dark, and a pair of thread-like antennae that are sensitive to touch and smell. The downward-directed mouthparts are …
Biology
Most grasshoppers are polyphagous, eating vegetation from multiple plant sources, but some are omnivorous and also eat animal tissue and animal faeces. In general their preference is for grasses, including many cereals grown as crops. The digestive system is typical of insects, with Malpighian tubules discharging into the midgut. Carbohydrates are digested mainly in the crop, while proteins …
Predators, parasites, and pathogens
Grasshoppers have a wide range of predators at different stages of their lives; eggs are eaten by bee-flies, ground beetles and blister beetles; hoppers and adults are taken by other insects such as ants, robber flies and sphecid wasps, by spiders, and by many birds and small mammals including dogs and cats.
The eggs and nymphs are under attack by parasitoids including blow flies, fles…
Relationship with humans
Grasshoppers are occasionally depicted in artworks, such as the Dutch Golden Age painter Balthasar van der Ast's still life oil painting, Flowers in a Vase with Shells and Insects, c. 1630, now in the National Gallery, London, though the insect may be a bush-cricket.
Another orthopteran is found in Rachel Ruysch's still life Flowers in a Vase, c. 1…
