Day 12: Today’s 30 Days Wild is going to be a ladybird hunt. Right or wrong I prefer to call them ladybugs!! On my daily walk with Riley we follow a path close to a railway line. At present the embankment is full of nettles and I’ve seen shinning red against the greenery, lots of ladybugs. Native or not (harlequin) I’ve decided to take a count of how many ladybugs I see on my walk.

On today’s walk I spotted a grand total of 24 ladybugs, a mixture of native and harlequin. In one section of the walk there were an abundance of ladybird larvae. They do seem to like nettles and knapweed.

It looks like the photos I have captured are all harlequin ladybugs, however I have seen some two, seven spot and 16 spot ladybirds during my count. I find it quite hard to tell native ladybirds from harlequins. Maybe the white eyes are a give away?

There are around 40 native ladybirds in the UK. Their redness is a sign to predators that they bitter tasting, they also exude a liquid that detracts birds and ants. Adults hibernate in winter. Their larvae are voracious aphid eaters.

Harlequin ladybirds are from Asia and arrived in the UK in 2004. They are more prevalent in towns, hence seeing more in a local park. They are larger than the native ladybird and out compete natives in prey and will eat other ladybird’s eggs and larvae.

Have you seen any ladybirds where you live?

Thanks for reading, and stay wild!

Day 24: For the last Close Up Monday of 2019’s 30 Days Wild, I am focusing on dragonflies.

My interest was piqued after reading that these large, colourful insects spend most of their larval stage in water. When they emerge as adults they shed their exoskeleton and are found clinging to nearby foliage for two hours whilst they pump blood into their wings for flight.

There are three stages to the life cycle of a dragonfly: egg, nymph and adult.

egg: mating occurs whilst flying and afterwards the female will lay her eggs on or near water.

nymph: or larvae is the longest stage of the dragonfly life cycle and can take up to four years. During this time the nymph is aquatic and eats other nymphs.

adult: once the time and conditions are right the nymph will crawl out of the water and shed it’s exoskeleton or exuvia, whilst resting on a plant. On the wing they look for food (they are voracious hunters) and to mate (to begin the cycle again). The lifespan of an adult is two months.

There are 23 species of dragonfly in the UK. Along with damselflies, dragonflies are of the Odonata order, meaning ‘toothed jaws. Both species have four sets of wings. Dragonflies can beat each pair of wings together or separately, and can fly at almost 30mph. They breathe through spiracles in the side of the abdomen. Dragonflies predate on flies, mosquitoes, bees and butterflies. Dragonflies have the largest eyes of the insect world and 80% of their brain is devoted to vision.

It was during the hot summer of 2018 when I saw the most dragonflies.
