*****

The top gallery shows Ladybirds of several species overwintering on one of our waymarker posts up Greenhill Way. Sightings have been made on this and other waymarkers over a number of years. So why did they gather like this?

Turns out that the first one to arrive releases pheromones that act as an advertisement to other Ladybirds looking for a hibernating spot. As they gather together the release of pheromones increases until the numbers max out.
The advantage is a certain amount of protection from predation through safety in numbers and the proximity of a suitable mate when they emerge from hibernation in the spring.
Say hello to them as you pass quietly - the kids are asleep🐞

True Bugs - Order Hemiptera

The Order Hemiptera, the True Bugs, are divided into two very different sub-orders, the Heteroptera and Homoptera, those differences apparent in the following sections.

In February 2021, using the BTO Acoustic Pipeline on a recordings made in 2019 1n 2020 - Steven & Ruth Budd found a Dark Bush Cricket in the lower section of The Wend and Great Green Bush Crickets at some distance. These findings are tentative as the accuracy level of the classifier is unknown and as these were identified from ultrasound recordings there was no photograph. However, the 2022 sighting provides additional confirmatory evidence of the Dark Bush Cricket.


Spiders

Orb Web Spiders

These spiders spin the familiar circular web and wait for their prey to get entangled.  Some species prefer  to wait centrally under the web, while others prefer to hide out of sight at the edge of the web with a foot touching a radial web strand, ready to dash out at the slightest twitch.

Crab Spiders

There are two types of crab spiders, the Thomisidae which hide and grab prey which arrives, like the Diaea, Misumena and Xysticus, and the Philodromidae Running Crab Spiders which chase and grab their prey with their crab like front legs.   All the crab spider species are quite small but can deal with much larger prey.

Harvestmen

Eight legged and often confused with spiders, Harvestmen do  belong to the class Arachnida (like spiders) but are in the order Opiliones whereas spiders are members of the order Araneae. Main differences are that Harvestmen have a one-piece body, no abdomen, a mouth that eats (which no spider has) and they do not produce silk.

Pond Creatures

Pond Creatures include animals from many of the species categories on this page but as they are found in a very specific habitat they have also been grouped here. All have been found in the ponds in the Jubilee Plantation or Linden Glade.
See also the sequence showing the development of tadpoles shown in the Amphibians section at the top of the page.
