The primary host plant for red admiral larvae is the native stinging nettle, ongaonga (Urtica ferox), although larvae can also eat other Urtica species. Throughout their life they use the nettle leaf to protect them during the day, by rolling the edge around them, or (as they get bigger) folding the leaf over into a 'tent'. [2]
Urtica dioica, often known as common nettle, burn nettle, stinging nettle (although not all plants of this species sting) or nettle leaf, or just a nettle or stinger, is a herbaceous perennial flowering plant in the family Urticaceae. Originally native to Europe, much of temperate Asia and western North Africa, [2] it is now found worldwide.
Typically found in moist woodlands, the red admiral caterpillar's primary host plant is the stinging nettle (Urtica dioica); it can also be found on the false nettle (Boehmeria cylindrica). [6] The adult butterfly drinks from flowering plants like Buddleia and overripe fruit. Red admirals are territorial; females will only mate with males that ...
Mowing weakens stinging nettle by decreasing leaf mass and limiting root growth. It also eliminates spread by seed. Mowing is an effective method for controlling stinging nettle growing in ...
Bird control or bird abatement involves the methods to eliminate or deter pest birds from landing, roosting and nesting. Bird control is important because pest birds can create health-related problems through their feces, including histoplasmosis, cryptococcosis, and psittacosis. [1] Bird droppings may also cause damage to property and equipment.
Stinging hairs of Urtica dioica (stinging nettle) A stinging plant or a plant with stinging hairs is a plant with hairs on its leaves or stems that are capable of injecting substances that cause pain or irritation. Other plants, such as opuntias, have hairs or spines that cause mechanical irritation, but do not inject chemicals.
Tortoiseshell butterflies tend to be unpalatable to birds. If a bird sees this bright red colouring, then they will be less likely to eat the butterfly. [14] The tortoiseshell butterfly is particularly fast. When discovered and attacked by a predator the tortoiseshell butterfly will fly away in a straight line in order to outstrip the predator ...
Stems will vary in between being smooth and covered in stiff hairs (glabrous to strigose), but have few of the stinging hairs the plant is known for. [ 4 ] The leaves of Urtica gracilis are variable, elliptic , lanceolate , or ovate , and 6–20 cm long by 2–13 cm across, with a base that can either be rounded or shaped like a heart ( rounded ...
