8 Facts About the Spiny Flower Mantis

Sure, you've heard of the Praying Mantis. But have you met its cousin, Pseudocreobotra wahlbergii, also known as the Spiny Flower Mantis? We stumbled upon its photo during an image search and had to find out more. Here are a few things to know about this beautiful, terrifying-looking insect. 

1. This tiny bug measures between 1 to 2 inches and is native to Southern and Eastern Africa.

2. Nymphs, like the one shown above, have an upturned abdomen. Adults have a large yellow spiral eyespot on their forewings.

3. When they're first born, nymphs are mostly black and look almost like ants.

4. Nymphs will molt approximately every two weeks; the time between molts gradually increases as the mantids get closer to adulthood. During molting, a mantis hangs upside down, sometimes shaking, and eventually wiggles out of its skin. It takes seven molts for a female to reach maturity, and six molts for males.

5. When threatened, the insects raise their forewings, which makes them look like a much larger creature with big, golden eyes. This is called a deimatic display, and it looks like this:

I wouldn't want to run into that guy in an alley—would you?

6. Instead of searching for prey, P. wahlbergii prefers to snatch its meals—usually pollinating insects—from the air:

7. Females have small spines on the edges of their wing cases; males do not. The male has slightly longer antennae and eight segments on its abdomen (females will have six or seven). An easy way to tell males from females is to look at the length of their wings: A female's wings will reach to the end of her abdomen, while a male's wings will extend past it.

8. Like other mantis species, the Spiny Flower Mantis is cannibalistic. As usual, it's the males who have the most to fear; the website MantisKingdom.com recommends feeding the female before putting a male in the cage behind her:

As she is busy with eating, she can't grab him or throw him off of her. After a while of holding on, the male will bend his abdomen down to connect with hers and mating will commence.

After the deed is done, the site suggests getting the male out of the cage quickly, or else he'll become a meal.

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.

UK Agrees to Ban Pesticides That Destroy Bee Populations

As bee populations around the globe continue to dwindle, more countries are stepping up to save them. The latest nation taking action against the threat of pollinator decline is Britain. The UK’s environment secretary Michael Gove recently announced that the country will join the European Union in restricting a type of pesticide harming bees.

The decision was made in light of a German study reporting that the number of flying insects in some areas have declined by 75 percent in just a quarter of a decade. Of the species dying off en masse, bees are the most concerning: The insects pollinate a significant portion of our crops, and without them humans could face an agricultural crisis. “These particular flying insects are absolutely critical to the health of the natural world,” Gove wrote for The Guardian. “Without a healthy pollinator population we put the whole ecological balance of our world in danger.”

The alarming state of bee populations is likely a mix of several factors, but human-made insecticides are one of the biggest contributors. Neonicotinoids, the chemical compounds covered by the proposed ban, are the most commonly used insecticides on Earth, and they’ve also been shown to have devastating effects on bee colonies. Getting rid of them completely was first proposed by the European Union in 2013, and after initially opposing the move, the UK is finally getting on board.

Neonicotinoids are slowly being phased out in the U.S., where beekeepers have been reporting bees disappearing from their hives for the last decade or so. If you want to make your backyard a more hospitable place for your tiny, flower-loving neighbors, here are some ways you can help right now.
