Characteristics

Ips grandicollis adults are small, cylindrical beetles measuring roughly 2.8 to 4.7 mm in length.[7] Their coloration ranges from reddish-brown to black, and the elytra display a steep declivity edged with five distinct spines on each side.[7] The body is approximately 2.5 to 2.7 times longer than wide, with the pronotum measuring 1.1 to 1.3 times its width.[8]

Their eggs are pearly white, oblong, and approximately 1.0 mm long by 0.5 mm wide.[7] Larvae are creamy-white, legless, C-shaped grubs reaching up to 5 mm, with reddish-brown heads under 1 mm wide.[7] Pupae are exarate, waxy-white, roughly adult-sized, with free appendages, forming in cells at the termini of larval galleries.[7]
