6 Cool Insects You Can Raise at Home

Don't let Mother Nature have all the fun!

1. Monarch Butterflies

Raising monarchs is super easy. If you don't have a patch of milkweed handy, order the plants online and plant them outside in clusters of three or more plants. Check the undersides of the leaves for eggs and tiny caterpillars. When you find a caterpillar, dig up the milkweed plant, wrap it in tulle netting from the fabric store so the caterpillar won't get away, and bring it inside to watch it develop. (You can order the caterpillars online, too.) It will eat like crazy for about ten days until it pupates. If you're raising more than one, you'll need additional milkweed plants. After the butterfly has emerged from the chrysalis, release it outside. Monarch Watch has detailed instructions about rearing monarchs, and you can order tags for your butterflies if you want to help track their migration.

2. Silkworms

Silkworms need mulberry leaves to eat, or you can order powdered artificial silkworm chow online along with the eggs. I asked around until I found a friend who had raised silkworms before, and she gave me a batch of eggs to keep in my fridge during the winter. When the mulberry tree in my yard started leafing out, I removed the eggs from the fridge. They hatched about nine days later. They should start to spin cocoons in a few weeks. This site shows a nice set-up using plastic deli trays and toilet paper rolls.

3. Crickets

Remember the children's book, The Cricket in Times Square? Crickets are charming and have been kept as pets in China for hundreds of years. If you can't catch a cricket in your house or yard, most pet stores carry them as food for larger animals. You can order a little cricket cage online, or use a jar with holes punched in the top. Place a piece of damp sponge in there so they can stay hydrated, keep them in a warm spot, and feed them scraps of fruits and veggies. Voila. Pet cricket.

4. Ladybugs

Whether you catch a ladybug yourself or order ladybug larvae from the internet, these are also pretty easy to care for indoors for a short time. Like crickets, adult ladybugs need a damp paper towel or sponge to drink from. Aphids are their favorite food, but if you're only keeping your ladybug for a few days it can get by on fruit. Tip: Milkweed tends to get covered in aphids. If you're already growing milkweed for your monarchs, bam. Ladybug food.

5. Black Swallowtail Butterflies

These gorgeous creatures like to lay their eggs in common garden herbs, including parsley, dill, and fennel. If you want to try to observe their life cycle, plant a big clump of parsley in a pot and keep an eye out for caterpillars, which are green with yellow and black markings and just as beautiful as the mature butterflies. If you have cats, tie some tulle netting around the pot so the caterpillars won't get eaten or crawl away. The black swallowtail chrysalis looks like a piece of bark or a small stick, so they can be hard to spot. I haven't had terribly good success with these, but a friend of mine raises them successfully every year.

6. Praying Mantises

These guys are crazy. Not only does the female often devour the male after mating, but the babies devour each other if given a chance. I bought a couple of praying mantis egg cases (they're about the size of a small marshmallow, and beige in color) at a garden fair once. I kept them in my garden shed and checked them regularly until I saw a million billion babies in the container, and then I set them free in my garden in hopes that they'd keep pests down. You can raise them in a small aquarium too, or buy a kid-oriented kit. Like betta fish, they need to be kept in separate containers to prevent a fight to the death. Other requirements: Sticks to climb on, and plenty of bugs to eat. This is a little involved for me, but if you're into carnivorous beasts, knock yourself out.

Finnish Food Company Launches The World's First Insect-Based Bread

A Finnish food company has created a protein-packed bread using an unusual natural ingredient: crickets. It's billed as the world's first insect-based bread to ever be sold in stores, according to Reuters.

In September 2017, Finnish officials approved the cultivation and sale of insects as food. But Fazer Food Services in Helsinki has been testing a bread that contained flour, seeds, and "flour" made from dried crickets long before than decision. The company waited for Finland to give bug food products the go-ahead before officially launching their product in late November.

"We wanted to be in the forefront of food revolution," said Markus Hellström, Fazer Bakery Finland's managing director, in a news release. Plus, he added, "Finns are known to be willing to try new things, and the Fazer Cricket Bread is an easy way to get a feel of food of the future."

A single loaf of cricket bread will set customers back nearly $5. Each contains around 70 crushed crickets, which are currently sourced from the Netherlands. Currently, there's not enough cricket flour for Fazer to conduct nationwide sales, so the company is rolling the product out in stages. Just 11 locations in the Helsinki metro area sell Fazer Cricket Bread right now, with plans to eventually offer it in all 47 Fazer in-store bakeries.

Cricket bread has more protein than the typical baked good, plus it's believed be more environmentally friendly to boot. And Fazer company officials believe that Finns, in particular, are willing to bite.

The world "needs new and sustainable sources of nutrition,” said Juhani Sibakov, Fazer Bakery Finland's director of innovation, in the statement. “According to research, of all the Nordic countries, Finns have the most positive attitudes towards insects.”

Which Rooms In Your Home Have the Most Types of Bugs, According to Entomologists

Insects can make any home their own, so long as it contains cracks, doors, and windows for them to fly, wriggle, or hitchhike their way in. And it turns out that the creepy crawlers prefer your living room over your kitchen, according to a new study that was recently highlighted by The Verge.

Published in the journal Scientific Reports, the study looked at 50 homes in Raleigh, North Carolina, to measure their insect populations. Entomologists from both North Carolina State University and the California Academy of Sciences ultimately discovered more than 10,000 bugs, both alive and dead, and a diverse array of species to boot.

The most commonly observed bugs were harmless, and included ladybugs, silverfish, fruit flies, and book lice. (Luckily for homeowners, pests like bedbugs, termites, and fleas were scarcer.) Not all rooms, though, contained the same distribution of many-legged residents.

Ground-floor living rooms with carpets and windows tended to have the most diverse bug populations, as the critters had easy access inside, lots of space to live in, and a fibrous floor habitat that could be either a cozy homestead or a death trap for bugs, depending on whether they got stuck in it. The higher the floor level, the less diverse the bug population was, a fact that could be attributed to the lack of doors and outside openings.

Types of bugs that were thought to be specific to some types of rooms were actually common across the board. Ants and cockroaches didn’t limit themselves to the kitchen, while cellar spiders were present in all types of rooms. As for moths and drain flies, they were found in both common rooms and bathrooms.

Researchers also found that “resident behavior such as house tidiness, pesticide usage, and pet ownership showed no significant influence on arthropod community composition.”

The study isn’t representative of all households, since entomologists studied only 50 homes within the same geographical area. But one main takeaway could be that cohabiting bugs “are an inevitable part of life on Earth and more reflective of the conditions outside homes than the decisions made inside,” the researchers concluded. In short, it might finally be time to make peace with your itty-bitty housemates.
