 SINGAPORE- 20 OCT 2026: 6 pm. Euscyrtus concinnus (commonly known as the Asian bush cricket) is a small, slender insect with a distinctive pale brown to tawny coloration and a sharply triangular profile when viewed from above. The length ranges from 1.0 to 1.8 cm. The head is primarily yellow but turns brown on top, accented by two distinct dark/livid lines running down it. Like most bush crickets, they sport exceptionally long, thread-like antennae that extend past the length of their body.

Physical Characteristics

Size: Adults are relatively small, ranging from 1.0 to 1.8 cm (0.4 to 0.7 inches) in length. Females are noticeably larger than males.
Body Shape: They feature a slender, narrow body plan with an elongated, smooth pronotum (the plate covering the top of the thorax).
Head & Antennae: The head is primarily yellow but turns brown on top, accented by two distinct dark/livid lines running down it. Like most bush crickets, they sport exceptionally long, thread-like antennae that extend past the length of their body.
Wings: Their wings are unevenly layered. The elytra (leathery forewings) are a dull, livid brown and cover only about two-thirds of the abdomen, coming together at pale lateral angles. However, their membranous hind wings are highly developed—measuring more than twice the length of the forewings and extending far past the tip of the abdomen.
Legs: They have long, tawny-colored legs built for jumping. The hind thighs (femora) are long and end in a very narrow tip, while the hind shins (tibiae) feature 9 distinct spines lining each side.
Female Ovipositor: Adult females have a prominent, straight, spear-shaped egg-laying tube (ovipositor) extending from the rear of the abdomen, which is roughly equal to the length of their entire body. [1, 2, 3, 4, 5]

Life Stage Differences

Nymphs (Juveniles): The young nymphs are also pale brown but lack fully formed wings, carrying small wing pads instead. They can be specifically identified by a pair of dark brown to black spots tracking along their abdomen.
Eggs: Their eggs are shaped like elongated ovals. They look completely white when first laid, turning an amber-orange color as they age.
