Pericyma cruegeri, the poinciana looper, is a moth of the family Erebidae. The species was first described by Arthur Gardiner Butler in 1886. It is found in south-east Asia including Hong Kong, Taiwan, Vietnam, Thailand, Sumatra, Peninsular Malaysia, Borneo, the Philippines, New Guinea, and in Australia, northern New South Wales and Queensland. Furthermore, it is an introduced species in Hawaii and Guam, where it was first detected in 1971. In Japan, it was first detected in 1986 in Ishigaki Island and the living area is expanded to Okinawa Island by 2000.[1]
The wingspan is about 40 mm. Adults are brown with a complex pattern of dark lines and patches, and often with some white areas. They are very variable in coloration.
The larvae feed on the foliage of Caesalpiniaceae species, including Peltophorum pterocarpum and Delonix regia[2] and can cause extensive damage. They feed communally at first but separate when older.
Pupation occurs in a cocoon covered in debris on the ground some distance from the food plant. The cocoon has a length of about 20 mm.

ホウオウボククチバ（鳳凰木朽葉。学名 Pericyma cruegeri）は、チョウ目ヤガ科シタバガ亜科に分類されるガ。
成虫は暗褐色と灰褐色が混じった羽根を持ち、樹皮に似た複雑な模様を持つ。色は地域によって変異する。開長は約40mm。ほぼ正三角形に羽を横に広げた状態で止まる。
幼虫は、頭が橙色、体は灰色を呈している。食樹はジャケツイバラ亜科のホウオウボクやコウエンボクで、葉を大量に食べて被害をもたらすことがある。
食樹の周りの落ち葉に長さ約20mmの繭を作り、中で蛹となる。
台湾、ベトナム、フィリピン、インドネシア（スマトラ島、ボルネオ島）、オーストラリアなどに分布[2]。1986年以降、日本の石垣島や沖縄本島でも確認されており定着している[2][3]。1971年以降、アメリカ合衆国のグアム島やハワイ州でも見つかっている。
日本では、国外からの侵入害虫として1986年に石垣島でホウオウボクに大発生したのが初記録となっている[2]。
ホウオウボクはマダガスカル島原産の樹であるが、街路樹や公園樹として沖縄県の各地で導入されており、ホウオウボククチバの幼虫による食葉被害が問題となっている[2]。
2000年には那覇市や浦添市で局地的に大発生[2]。2016年11月には那覇市でホウオウボククチバの幼虫が異常発生している[4]。
ホウオウボククチバには毒性は無い[5]。しかし、幼虫は街路樹などとして植栽されたホウオウボクの葉を食害[4]し、経済害虫となる。また、まとまった数が都市部で発生するため、不快害虫となる。
