Invasive ladies...
Our office was swarming with these nasty critters last year. They are Harlequin Ladybirds. On a plus they do eat aphids BUT so do our native ladybirds and these are the ones who are under threat.
In general Harlequin Ladybirds are larger and have more spots that our native ladybirds.
Think you've found one? The University of Cambridge, CEH and Anglia Ruskin University are doing a survey of Harlequin ladybirds. You can use your mobile or the web to record your sightings. Just click here to find identification sheets and more info. Another great site for native ladybird fans is http://www.ladybird-survey.org/

Pest and Diseases

Now is a good time to get on top of Pests and Diseases that will start to flourish in the warmer weather.

Pinch out the tips of broad beans once they start to flower. This helps to discourage blackfly, which otherwise can decimate tender new growth. Also keep an eye on brassicas and other vegetables, which pigeons love to destroy! Cloches, frames of netting or fleece and similar covers will help to keep them away from vulnerable crops. Finally check roses for signs of blackspot, aphids (shown above on an Aquielgia leaf) and leaf-rolling sawfly damage.
