Ireland has several native species of carnivorous plants, growing in bog habitats. (Please don't collect them and bring them home: it's unlikely they'll survive such an upheaval.)
These include three sundews (Drosera sp.), which lure insects by hairs beaded with "nectar" - in fact a sticky enzymatic secretion that traps and digests the insects. The three butterworts (Pinguicula sp.) have pale-green, waxy-looking leaves, covered in glands that exude mucilaginous enzymes, which, again, break down and digest their prey.
Bladderworts (Utricularia sp.), of which we have four species, are free-floating aquatic plants with tiny bladder-like traps on their stems. The traps operate by a vacuum action that is triggered by hairs: water fleas and other aquatic creatures are sucked in at great speed.
The Canadian pitcher plant (Sarracenia purpurea), introduced to Irish bogs about a century ago, has naturalised in various places. The Irish Peatland Conservation Council believes this vigorous alien is a threat to native flora, as it presents unfair competition to indigenous plants such as cranberry, ling and bog asphodel.
