Lacewings

Lacewings are beneficial insects that love to eat aphids, thrips, beetles, small caterpillars, and soft scales. They play an integral role in agricultural pest control, from small backyard gardens to extensive farms. Lacewings are part of the insect order Neuroptera. All immature insects in this order are predators of other insects. Lacewing adults are 8 to 25 mm long, have delicate clear wings with many veins, and at rest they hold their wings over their body. Most lacewing adults feed only on pollen, nectar, and honeydew, but one type of green lacewing will feed on small insects as an adult. There are many different types of lacewings, separated into two larger groups of green and brown lacewings.

One of the most fascinating facts about green lacewings is that

females lay their eggs on ½-inch stalks, either individually or in groups. The stalks may help protect one newly-hatched larva from being eaten by another and also reduces the risk that the eggs or developing larvae may be parasitized. Lacewing larvae, the immature stage of the insect, have a pair of strong jaws to capture and feed on their prey. The larvae impale the prey with their muscular jaws and lift it high in the air. Lacewing larvae are brown in color and are sometimes described as resembling tiny alligators. Another name for a green lacewing larva is an ant lion. These insects undergo complete metamorphosis. The larvae spin silken cocoons around plant stems or leaves during the pupal stage. Adults or pre-pupae overwinter depending on the species, with most species overwintering in cocoons and adults emerging in the spring. There may be multiple generations per year.

Did you know that lacewings have well-developed hearing? They can detect predators such as bats from great distances, and they will quickly drop to the ground to avoid being eaten. These beneficial insects also use their bodies to make vibrations and attract mates of the same species.

Wild and Wonderful Insects of New England

Toward the end of spring and the beginning of summer, I find that the most interesting insects are to be found. While spring offers some really good forester caterpillars and their attractive moths, among other things, nature seems to me to save the best for last, it seems to me. From beetles to butterflies, moths and their caterpillars, from June on there are some fabulous finds out there.

I have to admit to being a caterpillar enthusiast, and am partial to the sphinx, dagger, slug and prominent caterpillars and then the butterfly cats as well. Last year the swallowtail butterflies were few and far between, but this year our three main species- black, spicebush and tiger- are clearly more numerous. If you know where to look, you can find them.

I like to turn over elm leaves and search for two really spectacular caterpillars. The first is the double-toothed prominent, whose projections along its back resemble those of a stegosaurus. Along with its striking coloration and patterns, this is a truly remarkable find for anyone who takes the time to look and see. The second one is the elm sphinx, sometimes called the four- horned sphinx. This caterpillar has both a brown and a green form, and has little ridges running along its back. It is a behemoth, as well, like many sphinx caterpillars- robust and heavy.

Bug Week Offers Programs for the Whole Family

UConn Extension’s Bug Week is right around the corner, and we have programs for the whole family.

Bugs are the unsung heroes of our ecosystem, providing services such as pollination and natural pest control. However, bugs don’t stop at environmental benefits. They have also impacted our culture through the manufacturing of silk, sources of dyes, wax and honey production, food sources, and the improvement of building materials and structures. There are also problem bugs, like the Emerald Ash Borer and Brown Marmorated Stink Bug who are a concern in Connecticut. Visit our website at www.bugs.uconn.edu for featured insects and resources.

All ages are welcome to attend and explore the activities and events dedicated to insects and their relatives. Bug Week programs include:

–      Pests and Guests will be held at the Tolland Agricultural Center in Vernon on Monday, July 20th at 5:30 PM.Activities include: cooking with bugs, games and demos for the whole family, and learning about bugs in the garden. We still have a few spots available, please RSVP to bugweek@uconn.edu or call 860-870-6974.

–  Join UConn Extension faculty and Spring Valley Student Farm staff and students for an interactive, fun-filled ‘buggy’ event. Learn about our amazing and important insect friends by collecting and observing them. Activities for the whole family will include insect collecting, insect-inspired crafts and a scavenger hunt. This event will be held on Tuesday, July 21st from 9-10:30 am and 5:30-7 pm. The rain date is July 22nd. Both sessions will be offered in English and Spanish.

–       Dr. Jane O’Donnell, Manager of Scientific Collections, Invertebrates will offer tours of the Insect Collections in the Department of Ecology and Evolutionary Biology on Thursday, July 23rd. Times available are 10 AM, 10:30 AM, 2 PM and 2:30 PM. Please RSVP to bugweek@uconn.edu or 860-486-9228.

–       Find out all about insects and where to look for them in this UConn Bug Week event at the Museum of Natural History in Storrs on Saturday, July 25th from 1-3 PM. We’ll focus on Lepidopterans, the order of insects that includes butterflies and moths, but will see what other types of insects we can find too! This event will include a short indoor presentation with live specimens and an outdoor exploratory walk with tips on where to find a variety of insects in their natural habitats. Discover more Bug Week activities at http://bugs.uconn.edu.

UConn Extension offices are spread across the state and offer an array of services dedicated to educating and informing the public on innovative technology and scientific improvements. Bug Week is one example of UConn Extension’s mission in tying research to real life by addressing insects and some of their relatives.
