The structures found in large flowers such as those of Rafflesia and some Aristolochia are also evolved to attract and trap pollinators. [5] Trap-flowers that produce deceptive sexual chemicals to attract insects may often lack nectar rewards. Many fly-trapping flowers produce the smell of carrion. [5]
Felidae react to plants that contain nepetalactones by licking them and rubbing them in their fur. [5] Nepetalactones and nepetalactols repel some disease-causing insects. For example, nepetalactols are able to repel Aedes albopictus. [5] [1] The cats typically hunt other animals by stalking them. This requires being still or slow movements ...
Entomophily, pollination by insects, often occurs on plants that have developed colored petals and a strong scent to attract insects such as bees, wasps, and occasionally ants (Hymenoptera), beetles , moths and butterflies (Lepidoptera), and flies . The existence of insect pollination dates back to the dinosaur era. [13]
The bright leaves of the Venus flytrap (Dionaea muscipula) attract insects in the same way as flowers. Spiders can be the prey of aggressive mimics. The assassin bug Stenolemus bituberus preys on spiders, entering their web and plucking its silk threads until the spider approaches. This vibrational aggressive mimicry matches a general pattern ...
The insects attracted to the insectary plants will also help the other nearby garden plants. Many members of the family Apiaceae (formerly known as Umbelliferae) are excellent insectary plants. Fennel, angelica, coriander (cilantro), dill, and wild carrot all provide in great number the tiny flowers required by parasitic wasps. Various clovers ...
Entomophily or insect pollination is a form of pollination whereby pollen of plants, especially but not only of flowering plants, is distributed by insects. Flowers pollinated by insects typically advertise themselves with bright colours, sometimes with conspicuous patterns (honey guides) leading to rewards of pollen and nectar; they may also ...
The plants' ecological strategy varies; several species of Stapelia, for example, attract carrion flies that futilely lay their eggs on the flower, where their larvae promptly starve for lack of carrion. Other species do decay rapidly after ripening, and offer the visiting insects large masses of food, as well as pollen and sometimes seed to ...
Thermogenic plants are also protogynous, meaning that the female part of the plant matures before the male part of the same plant. This reduces inbreeding considerably, as such a plant can be fertilized only by pollen from a different plant. This is why thermogenic plants release pungent odors to attract pollinating insects.
