RSPB Sandy Insect Activity

As forecast, the sun came out and temperatures rose yesterday so there was plenty of activity around the banks to some of the paths at RSPB Sandy yesterday. This colony of Ivy bees were very active. I think they were mainly males but I did catch a female laden with pollen (wider abdominal stripes). Also recorded a Sphecodes bee (Blood Bee) - these are cleptoparasites (lay their eggs in another species' nest) - Ivy bees not recorded as hosts but there were presumably other mining bee species nesting in the bank  The small ponds on the walk were very active with lots of Ruddy Darters paired and laying eggs plus Migrant Hawkers and Southern Hawkers. The Gardens behind the house were quiet - just a handful of butterflies, a Firebug and a few Carder bees.

Ivy Patch Insect Cafe

 I have been asked by several people in our village what the bees are that are burrowing into their lawns, with similar questions on our local 'Next Door' and Facebook on-line sites including  how do you get rid of them? Ivy bees are harmless - they don't sting, digging their burrows can help aerate lawns and they will die after only a week or two so do not need anything done other than admire their smart stripes, chestnut furry thoraces and incredible industry. The bees collect pollen and nectar to provision their nests from the Ivy which is in full flower  at the moment.  These insects were from one small low ivy bush that I came across on my walk across to Bourn today. 

Hot Day in the Garden

A few more images from time spent sitting in the shade by my pond watching the insects visiting or living on the water. Honey Bees were the most frequent visitors drinking at the water surface to stay hydrated, feed larvae and regulate temperature to maintain optimal hive conditions, especially during hot weather. Worker bees collect water and spread it on the walls of wax cells, then fan it with their wings to create evaporative cooling, effectively air-conditioning the hive, crucial for brood development and preventing wax from melting!! Wasps similarly collect water and spread droplets over the nest structure, then fan their wings to promote evaporation   which lowers the nest’s internal temperature, protecting eggs and larvae from overheating etc They also need water to mix with chewed wood fibers to create a pulp that hardens into paper-like structures for their nests. Not many other insects showing themselves in the garden - mostly Shield/Plant bugs and Spiders!

RSPB Sandy 12th August

 A curtailed but enjoyable RPSNature outing to Sandy on Wednesday - those booked to come on the outing who lived a long distance away took the advice to postpone to a cooler time so just Chris and I braved the temperatures spending most of our time where we could stand in the shade photographing insects on sunlit plants. We concentrated on the Butterflies and Hummingbird Hawkmoths in the morning. In the afternoon, I hoped to get a range of Bee species on the heather to start to learn IDs for this group of insects but there were very few active in the intense heat so we decided it was wise to also abandon the open spaces and head for home!!
