Two-Striped Grasshopper

Fascinating facts about the Two-Striped Grasshopper

• Mating can stretch for up to ten hours, during which spermatophores are transferred continuously and the activity is mainly driven by the male. This prolonged union maximises both sperm delivery and nutrient provision, giving the female a protein boost. After copulation the female typically becomes receptive to another mate within four days, although she may wait as long as twenty-one days.
• During winter the grasshopper deposits its eggs in the soil, and they remain dormant until late April or early May when temperatures rise. When conditions are optimal, about 25 °C with high moisture, the embryos develop for roughly twenty-one days before halting growth and entering diapause. This pause allows the eggs to survive the cold season, with development resuming once spring returns and the soil warms again.
• When soil temperatures become sufficiently warm, the dormant eggs begin to hatch, and the highest hatching rate is observed between the tenth and thirteenth day after the process starts. This sharp peak means that most of the cohort emerges within that narrow window, synchronising the appearance of nymphs with favourable spring conditions. The timing ensures that the young have access to fresh vegetation as they begin their development.
• The two-striped grasshopper feeds on many plant types, from forbs to lentil crops, showing a highly polyphagous diet. When food is scarce it may even turn on its own kind, practising cannibalism. Crucially, its meals must contain linoleic or other unsaturated fatty acids, because these compounds prevent the delicate wing membranes from collapsing. Without them the wings would crumple and flight would be impaired.
• When temperatures drop below 25 °C the two-striped grasshopper ceases feeding altogether. The insect's metabolism slows so that fecal production falls dramatically, and the low temperature prevents the excretion of waste. This feeding halt is a direct response to the colder conditions, ensuring the grasshopper avoids the physiological stress of trying to eliminate waste when it cannot be expelled.
