B. Morphology / Distribution / Habitat Info

Morphology
Grasshoppers are medium-sized insects characterized by specialized features, notably their muscular long hind legs adapted for jumping. They possess chewing mouthparts, classifying them as herbivores, and have two pairs of wings, leathery forewings and membranous hindwings. Their life cycle involves incomplete metamorphosis (paurometabolous development), progressing through a simple sequence of egg to nymph to adult stages without a pupal phase 

Distribution
They are widespread across Asia, including Malaysia, where many species live in paddy fields, grasslands, and gardens.

Habitat Info
They thrive in warm, humid environments with abundant vegetation, making them common in areas such as paddy fields, grasslands, and gardens 

C. Traditional Uses / TK-related Info

▪ Food 

In parts of Malaysia and Indonesia, grasshoppers are consumed as a traditional food source, often being fried or roasted to create a protein-rich snack . This practice of entomophagy (insect-eating) aligns with global interest in sustainable, alternative protein sources, given the high nutritional value of grasshoppers, which are rich in protein and essential minerals.

▪ Cultural importance 

The creature holds a place in regional folklore, often appearing in children's songs, traditional stories, and folk sayings, with a notable example being the famous Malay folklore character, Pak Belalang 

▪ Traditional knowledge 

Beyond consumption, farmers and indigenous communities maintain traditional ecological knowledge (TEK) related to the insect, specifically associating an increase in grasshopper numbers with weather and seasonal changes, such as signaling the onset of dry spells 

D. Any related scientific studies, such as ecology/ conservation status/threats/diversity

Scientific studies show grasshoppers play crucial roles in ecosystems as herbivores and prey for birds, reptiles, and mammals. However, excessive populations can cause agricultural damage. MARDI studies have documented high species diversity in Malaysian rice ecosystems. Most species are abundant, though pesticide overuse poses a local threat to their populations.
