Ladybugs aren’t true bugs at all, they’re beetles. There are almost 400 different kinds of ladybugs in North America. Female ladybugs can eat as many as 75 aphids in one day, they also like to eat scale, mealybugs and spider mites. Ladybugs smell with their feet and antennae. A ladybug’s jaws chew from side to side instead of up and down like our jaws. The color of a ladybug’s spots begin to fade as it gets older. Ladybugs are most active when their body temperature is 75 degrees or warmer. A ladybug’s bright color warns birds that it does not taste good. When a ladybug flies, its wings beat 85 times every second. Female ladybugs are larger than male ladybugs. Aphids are the first pest to hit in the spring, and they love the new growth on plants. Buy your ladybugs now and keep them dormant in the refrigerator till your first outbreak of aphids, then release a few hundred at a time, preferably after sundown.
