Today’s animal is a No See Ums. These insects are also known as biting midges or sand fleas. They are small flies, and their adults are only around an eighth of an inch in length.
No See Ums are gray. Tiny hairs cover these insects’ wings, creating different patterns which enable entomologists to distinguish one species from another. Their larvae look like small, whitish worms or caterpillars. Just as their nicknames infer, you are unlikely to spot the No See Ums with the naked eye, especially those that have not fed.
No See Ums feed on plant nectar.
Their females also bite hosts and feed on blood, just as the female mosquitoes. The blood meal helps them in egg production. They lay eggs in moist environments.
These insects undergo complete metamorphosis with four stages. Their eggs hatch between two and seven days. Depending on the prevailing environmental conditions, species, and area, the larval stage can take as little as two weeks or as much as one year. The pupal stage takes between two and three days before the No See Ums become adults.
Even though the larval stage can last for up to one year, the lifespan of adult No See Ums is between two and seven weeks.
