Despite the rather blatant name of an ant, velvet ants are actually a family of wasps. While the “velvet” portion of the name refers to the bright colour their hairs have, the “ant” portion of the name refers to the females of the species not having wings like the males do. The bright colour is meant as a warning for potential predators.
This bright colouration is common in other small animals such as frogs or caterpillars, and is not just for show either. According to the Schmidt pain index, velvet ants rated at a 3, giving them another name — cow killer — and, much like their bright-coloured brethren, they sting only in defense.
The velvet ant’s exoskeleton is quite tough, allowing the female to invade the nests of ground-nesting bees or wasps to lay their young. They accomplish this by injecting their eggs into the larvae. The young hatch and consume the larva from the inside.
If you’ve read my post from October 7, 2016 titled “Insects & Agriculture (Part II)”, you may recall some info on the relation that ants and aphids have with each other. Well, just over the weekend, I spotted ants sitting in the leaves of an apple tree. They weren’t moving around too much: just pacing back and forth along the leaf. But as I looked more closely, I noticed tiny green bumps on the leaves. These bumps weren’t the regular bumps you see on tree leaves that indicate that insects have been eating away at them but were, in fact, aphids. You can see a couple of the (albeit blurry) photos I took right here.
Unlike the way ants treat almost every other creature in their vicinity, ants treat aphids with the utmost care. By letting the aphids suck the moisture from the plant, the ants are able to obtain the honeydew that is produced by the aphids. While the ants provide the aphids with protection and “greener pastures”, the aphids pay the ants with the sweetest drops of honeydew.
Slavery is one of those things that most, if not all, people look down on. Despite having such a negative light, it does increase productivity. People would capture slaves from neighboring/opposing factions and use them to perform the hardest labors, like farming and building. Societies where slavery was common, such as Ancient Egypt and many European countries became so reliant on slavery that the loss of slaves was actually detrimental to their society. Ants are no strangers to slavery either.
In some species, raiding is done quite commonly, where ants kill off rival colonies and take the larva for their own colony. However, there are a few species that take this step even further, but attacking ants of different species and bringing back the brood, dispute being different. The brood hatch and grow up believing that the colony they grew up in is their own, even helping its captors with future raids. It is a slave in a parasitic colony of ants. There are even parasitic ants that enslave adult ants of its hosts.
However, things aren’t all that bad. In some cases, slave-ants rebel and kill a lot of the parasitic ant larvae. This not only lowers that number of slave-makers but also saves the colonies from which they were taken.
There’s always been the question of “Should we modify DNA?”. Most people would say that it’s perfectly fine while others would say that it goes against religious beliefs. Personally, I believe that it’s a great technology to have and develop.
Just a couple nights ago, my family and I were discussing whether genetic modification was a positive or negative thing and, during the discussion, my father said this: “Genetic modification, like many other things, is like a blank canvas and what we do with it is what makes it good or bad.”
Much like the use of drugs can be used in a positive or negative way, the modification of something or someone’s genes can be for better or for worse. Modifying the genes of various food crops to be more resistant to disease, insects, and weather is very beneficial, not only to countries that have large populations but also to countries where food is a luxury.
Then there’s the question of where the line should be drawn. Should we stop at the modification of plant and animal DNA? Or should we stop at correcting a person’s DNA so they will be “normal”? Both of these points can be argued but here are my thoughts on the issue.
For the modification of plant and animal DNA, only modify the genetics of food products. Although there’re a number of people who believe that genetically modified foods (GMOs) are bad for your health, there has been absolutely no scientific study that suggest this. Not only does the modification of plant and animal DNA make food cheaper, it makes food more abundant for people who are desperate to get a morsel everyday.
In the case of modifying human DNA, I believe that we shouldn’t modify human DNA. There is great suffering that affected people may have to endure. But there are just as many who have actually learned to live with their disabilities and live fruitful lives. Famous movie/TV star Peter Dinklage, a “dwarf” (for those Game of Thrones fans), and well-known Christian speaker Nick Vujicic, who was born without arms and legs, have thrived despite their circumstances.
Domesticated animals are not new to anyone. We consume eggs produced from various birds and make products from the milk of cows, goats, sheep, and even camels. But just like how we weren’t the first to start growing crops, we weren’t the first ones to domesticate other organisms.
Ants require different categories of food, much like humans. They mainly require sugars as food, giving their larva protein from other insects or animals. However, there are limited numbers of sugar-sources. These include nectar from flowers, fruits, and seeds and they aren’t easy to secure.
Bees, flies, and even other ants make obtaining these basic resources difficult. To satisfy their needs, some ant species care for aphids–small insects that consume the leaves of plants. When aphids consume leaves, they ingest excess amounts of water. This water is pushed out of the aphids body and is known as honeydew. Due to having a high concentration of sugar, the honeydew is then distributed throughout the colony as energy.
