The release of insects feeding on the leaves and stems of L. dalmatica is an additional way to control the rapid reproduction of this plant and localize it to a certain area. The most prominent insect that aids in the suppression of L. dalmatica growth is the toadflax stem-mining weevil.
Trillium sessile is a perennial, clump-forming herbaceous plant with a thick underground rhizome.Like all trilliums, it has a whorl of three bracts (leaves) and a single trimerous flower with 3 sepals, 3 petals, two whorls of 3 stamens each, and 3 carpels (fused into a single ovary with 3 stigmas).

The 'toad' in toadflax may relate to the plants having historically been used to treat bubonic plague, a false link having been drawn between the words 'bubo' and 'Bufo'. The scientific name Linaria means "resembling linum " ( flax ), which the foliage of some species superficially resembles.
The western toad or boreal toad (Bufo boreas) is a large toad species, between 5.6 and 13 cm (2.2 and 5.1 in) long, of western North America. It has a white or cream dorsal stripe, and is dusky gray or greenish dorsally with skin glands concentrated within the dark blotches.
There are no true aboveground leaves but sometimes there are scale-like leaves on the underground rhizome. The bracts are photosynthetic and are sometimes called leaves. The inflorescence is a single flower with three green or reddish sepals and three petals in shades of red, purple, pink, white, yellow, or green.
Tricyrtis is a genus of Asian flowering plants in the lily family, with approximately 20 known species.The species are commonly known in English as toad lilies. The genus has a native range from the Himalayas to eastern Asia, including China, [3] Japan, [4] Philippines and Taiwan, [5] and a few species are cultivated for their ornamental qualities in other parts of the world.
While stomata can be found following the leaf margin on the lower surface of the plant's leaves, stomata on the upper surface of S. apoda leaves disperse entirely [6] following the laminae. [8] The dorsal leaves of S. apoda have acuminate apices. [9] The primary leaves of S. apoda significantly contrast in shape from the cotyledons of the plant.
The Gelastocoridae (toad bugs) is a family of about 100 species of insects in the suborder Heteroptera. These fall into two genera, about 15 species of Gelastocoris from the New World and 85 of Nerthra from the Old World. [1] They are reminiscent of toads both in the warty appearance and hopping movements of some species.
