荔椿 lychee stink bug

昆蟲實在是個浩瀚的家族,最近碰到一種椿象,翻查名字,椿象類別的繁多,又再次感受它們的蟲多勢眾。

過去幾個星期經過堅道,都在幾株攀長於一石牆的矮植物上發現它們 – 荔椿。荔椿的寄主植物是荔枝,但踪影不限於一種植物。這裡看到的便肯定不是荔枝或龍眼。

insects really keep me busy and add fun to any walk i take. the last few weeks, i found these buddies occupying a few plants sprouting along a concrete/stone wall on caine road. they are a type of stink bug of the common name of lychee stink bug. its host plant is lychee. but its survival does not bound by one plant and this is a proof; even though i cannot identity exactly what plant this is, it is surely not lychee.

lychee stink bugs are group insects. adults and nymphs share the same host.

the nymphs are of sharper appearance with contrasting red and white and black. the adults are orange brown in colour. their ventral edge and belly, feet and antennae are often seen covered with white wax.

荔椿的若蟲,顏色豔麗。成年後色澤比較踏實,呈橙褐色。腹側緣及腹面、各腳、觸角常覆滿白色蠟粉。它們屬刺吸式植食性,主攻果實、花及莖部。
