These insects are masters of camouflage
More than 3,000 different kinds of walking sticks live in the world, with the common walking stick being the most reported. A walking stick's eggs can be housed by ants and take a few months before a baby walking stick, or nymph, emerges. During their molting process, walking sticks have regenerative properties to regrow any legs it has lost. They have adapted for survival by using camouflage, being active at night, and by altering their rigidness to feel like a stick when fe


This snake is equally at home in water and on land
Northern water snakes live in and near water across Illinois. They grow 2 to 4 feet long, with females being larger than males. These carnivores eat fish, frogs, birds, and more, swallowing prey while they are still alive. Northern water snakes are non-venomous and are active by day in spring and fall and at night in summer. They have rough, keeled scales with banded backs. and can give birth to live young - up to 100 babies per litter. Though harmless, they may bite if threa


Harmless daddy long legs aren't spiders at all
All 6,000 species of Daddy long legs, sometimes called harvestmen, are not spiders and are more closely related to ticks and scorpions. Baby daddy long legs molt every 10 days and become adults in about a year. For defense, they spend more time hiding than crawling and have scent glands that release an unpleasant odor. They can also amputate a leg to run away from predators but will not survive very long without a pair of their sensitive, longer legs. They are completely harm


Firefly games to play in the dark
The activities Firefly Flash! and Firefly Tag are ideas from Cindy Blobaum’s book, “Explore Night Science!”. In Firefly Flash, players pick secret “boy” or “girl” cards with light patterns of dots and dashes on the back. "Girls" stay put and flash lights, while "boys" search for their matching light pattern. If unmatched, the "boy" is out. In Firefly Tag, players run from a tagger and must reach a flashlight or glow stick to be safe. If tagged first, you're out. Play continue


In living color: Do you see like animals do?
Humans see color through three types of cones for red, green and blue, but some people have two or even four. Many animals see differently. Bees and birds can see ultraviolet light, which helps them find food or mates. Reindeer use UV vision to find lichen and track predators. Butterflies may have the widest color range. Dogs and cats have only two cones. UV vision gives many animals a unique view of the world that humans can’t see.


Why do bees have pockets? For pollen, of course
Located on their back legs, some bees, such as honeybees, have pollen baskets, formally known as corbiculae, that act like pockets for them to store any pollen that has been collected. With the ability to hold up to 1 million grains of pollen, bees can visit more than 100 flowers on a trip before having to return to their hive. To help the pollen stay in place, bees will mix the pollen with nectar to make it sticky.


The mysterious mayapple and its poisonous fruit
Though mayapples, also known as the American mandrake, grow dispersed from one another in the spring and stand at about 1 foot tall, they all sprout from one underground rhizome stem, making them one giant plant grown from one seed. It takes five years for a mayapple to grow a rhizome stem and to start growing a big colony. They get their name from its white flower and the poisonous apple it produces. Every part of the mayapple plant is poisonous and will make you extremely s


Pretty punctuation: The question mark and Eastern comma butterflies
Eastern comma and question mark butterflies are easy to spot thanks to tiny punctuation-shaped markings on their wings. Both overwinter as adults so they are among the first butterflies seen in spring. They have two broods a year and look different by season. Their spiky caterpillars feed on elm hackberry and nettles. Adults drink from sap fruit and droppings. Look closely at their underwings to spot a silver comma or a question mark.


Bug out with these fun roly-poly facts
Pillbugs, also known as roly-polies and many other nicknames, are not really insects, but rather crustaceans. They are the only crustaceans that live entirely on land. They do not urinate due to their high tolerance for ammonia and also eat their own feces. Pillbugs are scavengers and serve as decomposers returning nutrients to the soil. Roly-polies pose no risk to humans.


Why don't fish freeze in the winter?
Ever wonder how fish survive winter in frozen lakes? Since they’re cold-blooded, their body temperature matches the chilly water. As ice forms, warmer water sinks to the bottom, and fish rest there, barely moving. They don’t hibernate but enter a low-energy state, needing little food or oxygen. When spring comes and the water warms, they become active again.


Groundhogs go by many different names
Groundhogs have several names including land-beaver, whistle-pig, and woodchuck. They are rodents and part of the squirrel family. They live in underground burrows and hibernate as early as late October up until February, around the time when Groundhog Day is celebrated. Despite being a tradition since 1886, no science backs up Punxsutawney Phil’s predictions.


Try this cool winter animal experiment
Test if your jello critters can survive winter with this experiment! Pour Jello into small containers. Just like animals need insulation and a warm place to live, build “homes” using materials like mittens, leaves, or bubble wrap for insulation. Place your Jello critters outside in their homes and leave one out in the open. After 30 minutes, check if they stayed liquid (survived) or turned into jello (died). See which homes kept your critters warm!


Butt-breathing snapping turtles are a real gas
Snapping turtles are cold-blooded and can absorb oxygen underwater in winter via a cloaca (their butt). This cloacal respiration helps them survive while brumating. Their shells neutralize acid buildup, and they can be aggressive on land. Known for snapping jaws, snapping turtles can’t fully hide in their shells. Two species exist in Illinois: the common snapping turtle and the endangered alligator snapping turtle, which are the largest of its species, weighing at 150 pounds.


The scoop on animal poop
All animals poop, and their droppings can reveal clues about their diet and lifestyle. Coyote scat may contain fur or bones and is used to mark their territory. Rabbits eat their droppings for extra nutrition. Deer poop is similar to rabbit droppings, only larger. Bat droppings, called guano, resemble rice grains. Goose poop is tube-shaped and is often green or white. Horses can produce up to 50 pounds of manure daily. Bird poop is mostly white uric acid, which doesn’t wash a


Beavers are big, busy rodents
Beavers are hardworking rodents known for building dams and lodges near water. They are the largest rodent in North America and can weigh up to 90 pounds. Beavers use strong orange teeth to cut trees and eat only plants. Baby beavers, called kits, can swim at birth. They live in family colonies and use their scaly tails for swimming, balance, and warning signals. Beavers can stay underwater for 15 minutes and have waterproof fur to help them thrive in wet habitats.


Create some compost in a cup
Composting is nature’s way of recycling living things into soil. Anything once living can break down into compost, which looks like dark, crumbly soil and smells like forest floor. You can make compost in a cup using organic scraps, soil, water, and sunlight. Mix the ingredients, cover the cup with plastic wrap, and place it outside. Add water and shake it every few days to help it break down. Over time, you’ll see your scraps turn into compost!
