Lesser Swallow Prominent - breeding success !


Female laying eggs 27th April. 12 collected from egg box others on fence could not be extracted though I eventually found 2 small caterpillars there on 19th May. The ones from the female hatched on 14th May

Initially very small cat's easy to lose, and left them in small plastic tubs and fed on birch leaves (host plant) with fresh leaves from the same tree every two days,. Length (approx) 3mm on 26th May, 20mm on 1st June. Changed to clean tubs every 3 days and kept in the garden hut.

 3rd June
 10th June



 15th June - now around 35mm - they went glossy and buried themselves in c80mm seed/cutting compost in ice cream tubs


Four adults emerged on the same day, 27th July - just 3 months after egg laying, and located themselves on the hut window. They flew off out of the hut a dusk




Think there could be seven more in the tubs, if they've  survived ? I'll wait and see, as they probably are the ones that went to pupate a day or so later than the others.
