Common Earwig

Forficula auricularia
The Common Earwig is also called the European Earwig, but that name is a little bit misleading. Though they did orginate in Europe and Northern Africa, they can now be found all over North America as well, thanks (or not thanks?) to introduction during the 20th century.

You can identify Common earwigs by their skinny bodies and large forceps on the abdomen (they are slightly larger in males). They use them to mate, to feed, and for self defense!

The Earwig lives in cool, moist, dark places, and is most active during the night time. Though they look a bit frightening, they are actually plant eaters a lot of the time. They feed on different leaves, flowers, lichens, and algae, though they do sometimes snack on insects and insect eggs.

Mother Earwigs are pretty good parents. She lays her eggs before it gets cold, and stays with them over the winter, burrowing just slightly underground. She even cleans them to keep them free from fungal growth. In the spring she moves them into a single layer to make hatching easier, and then she will actually guard over them until they reach maturity!

Common earwigs are considered pests in some areas, because they will feed on crops.

Bornean Orangutan

The Bornean Orangutan is one of two extant Orangutan species in the world. It is the third largest primate (after Gorillas) and is the largest primarily tree-dwelling animal in the world. Males are substantially larger than females, and average at around 165lbs. Bornean Orangutans are largely solitary. A handful might live within a small range but they will seldom interact with one another. Males and females only meet up to breed, which happens only once every several years. A young Orangutan will stay with it's mother for about five years, and the females tend to go about eight years between births. That is the longest interim period of any animal! Sadly, the Bornean Orangutans are in a lot of trouble. They need large forests in order to thrive, and deforestation and habitat degradation has left many homeless. They are also hunted for meat and for traditional medicines. Conservation areas are being established to help these guys in the wild, and it is believed that there are a

10 Years?!

My goodness! It's been 6 years since I went on hiatus, and now more than 10 years since AaD was born, and what a world we've moved in to! Animal a Day is coming back- but in the meantime, check us out on Facebook, for your daily dose of #BIRDNEWS


For anyone who was counting, yesterday was our birthday-- four years! Four years filled with animals from A to Z, more than 1,100 of them! I can't thank my readers enough, it's been wonderful! And in celebration of that milestone... I'm taking a break. Hopefully not forever, but for a little bit at least. In the mean time I plan on getting a new layout out, along with some updates to some of the older articles. I'll post updates here and on the Facebook page, I'm also brainstorming some new animal-related projects, so keep an eye out! Thanks again for four awesome years!
