Ideally, you want to move the animal without touching it. This is preferable because a lot of insects can sting, bite, or cover you in a smelly fluid.
Many insects and spiders, like moths, can be harmed if you handle them too roughly. An index card would be ideal, but notebook or printer paper will also work. Ideally, you should use a clear cup because you want to see when the animal is at the top of the glass. Both insects were released unharmed.
Picture credit: Joe Ballenger. Take it outside, and dump it out far away from your house and close to the ground. Releasing a bee or a wasp might be a little intimidating, but they tend not to sting unless you grab it and trap it. Would it be ok for me to capture her and relocate her with me so I can make sure that no one kills her or would this be too stressful for her?
As far as I can tell she does not have babies yet. I am only moving 5 hours from my current location and she would go into a garden at my new home. Catch the spider, like above, and simply include a little bit of web for it to hang on. You should use a pencil to transfer the web to a low-hanging plant. In this case, the best solution is to simply leave her wherever she lands. Pupae are pretty complicated, maybe even more so than the other insects. Leave them if you can, but if they need to be moved this is still possible.
One of them was good enough to anchor itself on the side of the jar. I know you can move a monarch chrysalis with a Q tip and water, but can you do the same with this species? A coocoon is pretty easy to move. Very gently feel the coocoon to see if the pupa inside is still there. Pinch the silk and lift up. The rest of the silk should come with it; the pupa still safe inside. After that, move it to a protected spot out of direct sunlight.
Note the white stuff at the top of the cremaster. Unfortunately, not all pupae have this. So be careful when relocating butterfly pupae. Chrysalises are probably the most complicated entry on here, because you need different tools. You also need to know a little bit about the biology of the pupa. The tools you need are simple ones.
Pupae are held onto a surface by a structure called a cremaster. It can be broken without harming the pupa. Second, use your blade to cut under the cremaster. If possible, shave the first layer of the substrate off. If the insect is on a plant, this is the best possible situation because you can simply remove the leaf. You want to gently scrape the cremaster off the substrate.
If done right, it will come off without a trace. For hunting spiders, the pair of eyes in front of the face, particularly the largest ones, are called anterior median eyes AME or direct eyes. AME are typically used for color and clear vision whereas the secondary eyes are responsible for night vision , peripheral vision and motion detection. They have sharp color vision even ultraviolet light and are good at distinguishing different shapes.
Their excellent eyesight enables them to hunt preys and identify mates and enemies. Other than having good eyesight, these superb hunters have almost degree of vision. Their eyes are arranged in three rows with four small eyes in front for direct vision. Tapetum tapeta for plural is a reflective membrane at the end of the retina which reflect light back to the retina so that the image is intensified. Wolf spiders are easy to be found at night because when you shine light into their eyes, their eyes glow as the light is reflected to back you.
Wolf spiders have excellent depth perception for objects at close range which make them deadly hunters. They are able distinguish ultraviolet light which cannot be captured by human eyes too!
Other than hunting, wolf spider vision is critical for identifying the opposite sex during courtship. Interesting Facts: Wolf spiders are wonderful mothers. Before laying her eggs, the female wolf spider will build a container on her body with spider webs so that she can carry the eggs around with her until they hatch. This nocturnal hunter from the Deinopidae family have eight eyes including two rear eyes PME that are enormously huge.
With their face curved forward, the eyes looked like two searchlights, giving the spider a menacing appearance. Do note that the net-casting spiders have eight eyes, the other four cannot be seen from the front view. With its size, these eyes are specialized for providing outstanding night vision. They have enormous, compound lenses that give a wide field of view and gather even the tiniest amount of light very efficiently. In fact, the lenses make web-casting spiders more superior in concentrating available light than a cat or an owl.
To enhance night vision , large amount of light sensitive membranes are produced in these spider eyes every night and rapidly destroyed in the day. Interestingly, net-casting spiders hunt in the light without the help of tapetum refractive tissue at the back of the retina.
Instead, they place white faecal spots on a surface across which prey animals are likely to walk such as a broad leaf and a tree trunk. Nope for majority of them. However, some have greatly evolved vision to cater for their hunting style which can be even more sophisticated than ours. Next time you see a jumping spider staring at you, it might be sizing you up.
