No, they are peacful
Yes, but they only bite small bugs like aphids and scale bugs. They don't bite humans, don't think they have the mandibles to even accomplish such a task!
Nope! :)
They eat aphids to live
Ladybugs are indeed helpful to humans, because they eat aphids, and aphids are damaging to many plants that we humans like to grow.
Yes, aphids bite people. Any insect with piercing, sucking mouthparts is capable of scratching skin surfaces just as they plant tissues. The experience will be more like getting a minor abrasion from a slightly rough surface than like having the skin broken by a bee, hornet, scorpion or wasp sting or a snake bite.
certain species of ants use aphids similar to how humans use cows: they lead them to graze and collect a liquid discharge the aphids excrete from their abdomen. ants also protect aphids from harm similarly to how humans keep their livestock safe from harm.
Aphids do not use humans as hosts. They are small sap-sucking insects that primarily feed on the phloem of plants. While they can affect agriculture and gardens by damaging crops and transmitting plant viruses, they do not have a parasitic relationship with humans. Instead, aphids typically rely on specific host plants for their nutrition and reproduction.
Yes a nice vampire might bite a humans
No. Plant lice is another name for aphids. These small plant feeding insects are of no relation to the blood feeding head lice that are commonly passed among children in elementary schools. They feed strictly on juices they suck from plants.
The nouns are: pest, humans, bite.
They don't bite humans.
The two can both be herded and 'milked' . Cows are domesticated by humans whereas aphids are used by some ants for the sweet secretion that the aphid exudes .
