False Autumn

Posted on by BITM

It might be the start of meteorological autumn but it’s still too early for leaves to start falling from trees; yet over the past few weeks this has been occurring. Referred to as false autumn, this leaf (and acorn) drop is occurring as a result of the extreme temperatures and drought we’ve experienced this year. It is a sign of stress as trees attempt to conserve water and energy. Current lower morning temperatures have also lead to an autumnal feeling. Thankfully we are now experiencing rainfall so perhaps this will prevent trees from showing further signs of stress even though it doesn’t stop us being in drought. Hopefully autumnal colour won’t be affected too much and we will still witness the spectacular seasonal colours this year.

A couple of weeks ago my partner and I went for a walk to spot Saturn ascending in the sky at dusk; we visited the local woodland park. At nine o’clock, on one of the hottest days of the year, the temperature was quite pleasant. As we walked through the woodland to an open area, where we could view the planet, we got to experience bats flying close by (the following videos is of some footage I managed to obtain).

Without a Bat detector, I have no way of correctly identifying the species out of the 18 that roost in the UK. According to the information I found on the Hertfordshire and Middlesex Bat Group website, the ones we most likely encountered in the area are either the Common Pipistrelle (Pipistrellus pipistrellus) or Soprano Pipistrelle (Pipistrellus pygmaeus). Regardless of the species, just experiencing the creatures flying nearby to capture insects was amazing. I haven’t witnessed bats in fight since I was a child.

It’s still possible to see some butterflies and bees at this time of year so late year flowering plants are essential.

White tailed bumblebees (Bombus lucorum), Buff tailed bumblebees (Bombus terrestris), Red tailed bumblebees (Bombus lapidarius), Common carder bees (Bombus pascuorum) and even some Honey bees (Apis mellifera) still forage in September. The Butterfly Conservation charity produced a photo (see below) of common butterflies and moths to see at this time of year.

During the previous week I was still noticing several Hummingbird hawk moths (Macroglossum stellatarum) too. These moths have been quite prevalent this year.

On one occasion I managed to get a video of a Hummingbird hawk moth visiting a Buddleia.

October Arrives

Posted on by BITM

The results from the UK’s Big Butterfly Count 2020 were released last week. This summer, between 17th July to 9th August over 1.4 million butterflies were counted. However, while the amount of people taking part increased, overall the average numbers of butterflies were down 34% from the previous year (and were the lowest average since 2009 when the first count took place).

One difference from the 2019 results was the amount of Painted Lady (Vanessa cardui) butterflies. Last year was great for this species as a huge migration of Painted Ladies arrived to the UK from the continent; this spectacle wasn’t repeated this summer. Whatever other reasons for the results this year, it does show the fragility of nature and how quickly things can change.

Yet there are things we can do to improve this situation in the future; for example, growing food for caterpillars as well as providing shelter and nectar. The Butterfly Conservation website provides helpful tips on how we can help butterflies within our gardens.

More information on the results, including the breakdown of the individual species, can be seen on the Butterfly Conservation website too (see here).

It is still possible to see Butterflies on sunny days, along with moths, even in this month as shown on the picture below (also provided by the Butterfly Conservation charity).

Butterfly Numbers Flying High.

Posted on by BITM

With Buddleia, Lavender and Verbena bonariensis in full bloom at the moment butterfly sightings have increased significantly.

Along with plenty of Peacocks (Aglais io), Red Admirals (Vanessa atalanta) and Large whites (Pieris brassicae), I noticed a few other butterflies last week.

The first was a Gatekeeper (Pyronia tithonus) visiting Shasta daisies (Leucanthemum × superbum),

but I also saw a Comma butterfly (Polygonia c-album) pollinating some Verbena bonariensis too.

Along with these butterflies, the European gypsy moth (Lymantria dispar) reappeared, still under the Rhubarb patch on the allotment (see my ‘All you Need is Love and Nature.’ post from the 29th June 2020). However it was no longer a caterpillar but in the next stage of its life cycle, a pupa hanging from a Rhubarb leaf.

It can be in the Pupal stage for a fortnight so I will keep checking for its emergence as the adult moth, so I can hopefully see it take place. As I don’t exactly know when the Pupal stage began I’m not sure how soon it will occur. The male and female moths look very different so can be easily identified, plus the females don’t fly (see Butterfly Conservation); therefore if no moth is found then it was probably a male that has flown away.

The last insect that was noticeable last week was a Common red soldier beetle (Rhagonycha fulva).

It is always great to see these beetles as the are beneficial insects which predate aphids while their larvae eat
invertebrate pests, slugs and snails.

A Chill in the Air with Beautiful Sunrises.

Posted on by BITM

Occasionally I am still surprised by nature. One instance of this occured on my way home last Monday when I saw a Heron (Ardea cinerea) standing on a rooftop. I had to double take to confirm it was real; thankfully it moved it’s head slightly. The house was near a river but I guess it was looking for an easy dinner from someone’s pond. Infact this wasn’t the only time I saw Herons during the week. On Wednesday I also noticed a couple flying above where I worked. One of them was calling but I think it was warning the other off because they eventually went their separate ways.

Jay’s (Garrulus glandarius) also became more visible last week as they harvested acorns before the squirrels (Sciurus carolinensis). I love the Jay’s colouring and the meaning behind their Latin name. Garrulous is a word that refers to their noisy chattering while glandarius translates as ‘of the acorn’, very appropriate.

Garden spiders (Araneus diadematus) seemed to be very busy creating their orb webs amongst perennials and shrubs; especially as I often managed to get my face tangled amongst them by accident (meaning their well deserved rest was cut short).

There was a chilly start to Thursday and I woke to a beautiful sunrise. Even though the temperature has dropped slightly, my Asters and Penstemon continue to flower well. Hopefully pollinators are still visiting them. I noticed some bees and a Red admiral (Vanessa atalanta) flying about in other gardens.

On Friday however, I saw
2 Box tree moths (Cydalima perspectalis). These pretty moths with a purply-brown pattern set against white wings were not such a welcome sight. This is the first year I have noticed these moths. I first saw their caterpillars in another garden during the summer too. It is the caterpillars that cause the damage as they defoliate Box (Buxus) plants. They are considered a pest and are spreading further across the country (for further information see Butterfly Conservation).
