Description
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. In warmer areas, such as the southeastern United States, the hatching is earlier, while for species such as the plains lubbers in the western parts of the country, later spring is the expected arrival time fo…
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. Young lubbers usually travel in large numbers, swarming and devouring plant material as they go. Knowing which plants they favor can help growers to be on the lookout for these pests; also…
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. Lubbers ingest and assimilate substances in the plants th...
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. If control of the young lubbers on host plants for which the insecticides are approved is the goal, chemical control is an option. Otherwise, these pests are best eradicated by hand. Because most spe…
