Lesser Treble-bar Aplocera efformata
Wingspan 35-41 mm.
Very similar to the Treble-bar (A. plagiata), but can be separated by its slightly smaller size, paler ground colour, and the shape of the inner wingbar, which tends to be straighter and more sharply angled.
The tip of the male's abdomen is also shorter and blunter than that of Treble-bar, with somewhat curved claspers compared to Lesser Treble-bar's straighter, more pointed abdomen tip. (See photo).
The species has a more southerly distribution than A. plagiata, being common only in the very south. It occurs less commonly gradually northwards to northern England. Like its cousin, the larvae feed primarily on St. Johns-wort (Hypericum spp.).
There are two generations, flying in May and June, then again in August and September.
Lesser Treble-bar Aplocera efformata Wingspan 35-41 mm Ni sawa na A. plagiiata, lakini inaweza kutenganishwa na ukubwa wake mdogo, rangi ya chini ya rangi, na umbo la wingbar ya ndani, ambayo huwa moja kwa moja na kwa pembe kali zaidi. Ncha ya tumbo la kiume pia ni fupi na isiyo na madoa kuliko ile ya Treble-bar, na vifungo vilivyojipinda kwa kiasi fulani ikilinganishwa na ncha ya tumbo iliyo sawa, yenye ncha zaidi ya Lesser Treble-bar. (Ona picha). Spishi hiyo ina usambazaji wa kusini zaidi kuliko A. plagiata, ikiwa ya kawaida tu kusini kabisa. Ni hutokea chini ya kawaida hatua kwa hatua kaskazini kwa kaskazini mwa Uingereza. Kama binamu yake, mabuu hayo hula hasa mimea ya St. Johns-wort (Hypericum spp.). Kuna vizazi viwili, vinavuka mwezi wa Mei na Juni, kisha tena mwezi wa Agosti na Septemba.
