I have put together this photo gallery of the aphid species I’ve found as a companion piece to my previous Blog ‘A is for Aphids’ (https://arthropedia.co.uk/a-is-for-aphids/). More species will be added as I find them. It is arranged by host plant, with tree species listed first. Note that while many species of aphid are host specific, others will feed on a variety of plants. The complex life cycle of aphids means that different forms can be found at different times of the year with some species producing winged individuals known as alates. Some species only produce females and reproduce parthenogenically. A colony of aphids will often have a mixture of adults and nymphs and sometimes have more than one species present.
I find a lot of different aphids in my local cemetery where a wide variety of both native and non-native trees have been planted. In abundant aphid years I often find lots of them on gravestones under trees, especially after rain or windy weather has knocked them off the foliage. Then the gravestones provide perfect hunting grounds for aphid predators like ladybirds and lacewing larvae.
