Elf'ing ladybugs are back . These are not the native type they are Asian ladybugs some say brought in to eat the Asian Hackberry Aphid . I think them and the Aphid's came in on the Asian schrubs the have became a invasive species also . The native ladybug is bright red with well defined black dots these invasive ones are a brunt orange color . They swarm everything in their path . Like little bulldozers push themselves through smallest cracks. Their a real pest .
