There are numerous bugs which live among us each summer and go without notice. This is especially true for those who mind their own business, don't bite or crawl through our houses.
The Green Lacewing is such a fellow. It is easy to miss. As the name implies, the wings are very fine works of lace. The eyes can be golden in colour. If they are resting on plants they are near invisible - about an inch long. Lacewings are rarely inside your house. Sometimes they give off an unpleasant odour when handled. I tend to leave them alone - the wings are just too easily damaged.
Lacewings, both as larvae and adults, are very beneficial in the garden - they feed on aphids. They pose no threat to people. Next summer enjoy these little pieces of lace, and let them go their way untouched!
