30 Days Wild – Day 12 – Here be Bees

Another mostly dull day, although dry, conditions that may seem not so good for finding insects, which is true, but if you find them they are much less active and so easier to see well.

On such days insects will often be found sitting in the open in the hope that the sun will come out and enable them to warm up enough to become active. Predatory species, if they can get active can then easily catch prey that has not warmed up so much. Robberflies are one such predator and several species are on the wing now.

Many insects will vibrate their wing muscles to increase their core temperature, bees have an added advantage of being furry which will help to reduce heat loss.

The cooler weather did encourage me to do some control of the bramble regrowth in the grassland in the former Hanson plant entrance, this area gets very hot in the sun, which should make it good for insects. The soil, if it can be called that is very poor, an advantage for establishing a non-grassy sward, but here it is so poor, that in places almost nothing will grow. This is in contrast to the bank of deeper soil just to the south where there are probably too many nutrients.

Despite having only been seeded three years ago and on soil spread from the old concrete block plant site it already has some quiet surprising species.

I assume the bee orchids must have been already in the soil, surely three years is too short a time for them to have grown from seed? There were only  a few but one was one of the variants, I think “Belgarum”.
