It is not true that aerodynamic theory predicts that bumblebees should not be able to fly; the physics of insect flight is quite well understood. The misconception appears to come from a calculation based on a fixed-wing aircraft mentioned in a 1934 book, and was further popularized in the 2007 film Bee Movie.
While certainly critical to the pollination of many plant species, European honey bees are not essential to human food production, despite claims that without their pollination, humanity would starve or die out "within four years". In fact, the most essential staple food crops on the planet, like wheat, maize, rice, soybeans and sorghum, are wind-pollinated or self-pollinating, and only slightly over 10% of the total human diet of plant crops is dependent upon insect pollination.
Bees do not always die if they use their sting. This happens for only a very small minority of species, which includes the honey bee, when they sting mammals, as they have thick skin. They are able to survive when they sting other insects.
Cockroaches would not be the only organisms capable of surviving in an environment contaminated with nuclear fallout. While cockroaches have a much higher radiation resistance than vertebrates, they are not immune to radiation poisoning, nor are they exceptionally radiation-resistant compared to other insects.
Not all earthworms become two worms when cut in half. Only a limited number of earthworm species are capable of anterior regeneration.
Earwigs are not known to purposely climb into external ear canals, though there have been anecdotal reports of earwigs being found in the ear. The name may be a reference to the appearance of their hindwings, which are unique and distinctive among insects, and resemble a human ear when unfolded.
Houseflies have an average lifespan of 20 to 30 days, not 24 hours. However, females of one species of mayfly, which do not belong to the group of true flies, have an adult lifespan of as little as 5 minutes.
Applying urine to jellyfish stings does not relieve pain and may make the pain worse. The best immediate treatment for jellyfish stings is to rinse them in salt water. For some kinds of jellyfish stings, adding vinegar helps.
 Female praying mantises do not always eat the males during mating.
The daddy longlegs spider (Pholcidae) is not the most venomous spider in the world. Their fangs are capable of piercing human skin, but the tiny amount of venom they carry causes only a mild burning sensation for a few seconds. Other species such as harvestmen and crane flies are also called daddy longlegs, and share the misconception of being highly venomous but unable to pierce the skin of humans.
People do not swallow large numbers of spiders during sleep. A sleeping person makes noises that warn spiders of danger. Most people also wake up from sleep when they have a spider on their face.
Though they are often called "white ants", termites are not ants, nor are they closely related to ants. Termites are actually highly derived cockroaches.
Ticks do not jump or fall from trees onto their hosts. Instead, they lie in wait to grasp and climb onto any passing host or otherwise trace down hosts via, for example, olfactory stimuli, the host's body heat, or carbon dioxide in the host's breath.

=== Plants ===
Carnivorous plants can survive without eating prey. Catching insects, however, supports their growth.
Mushrooms, molds, and other fungi are not plants, despite similarities in their morphology and lifestyle. The historical classification of fungi as plants is defunct, and although they are still commonly included in botany curricula and textbooks, modern molecular evidence shows that fungi are more closely related to animals than to plants.
Poinsettias are not highly toxic to humans or cats. While it is true that they are mildly irritating to the skin or stomach, and may sometimes cause diarrhea and vomiting if eaten, they rarely cause serious medical problems.
 Sunflowers do not always point to the Sun. Flowering sunflowers face a fixed direction (often east) all day long, but do not necessarily face the Sun. However, in an earlier developmental stage, before the appearance of flower heads, the immature buds do track the Sun (a phenomenon called heliotropism).
