Insect Highlights of 2023
With the new year celebrations scheduled for this weekend, I thought it best to share some of my favorite insect specimens from this year, rather than one single typed of insect. The pictures here haven't been uploaded to the blog in a post, so today they can all share the spotlight. There are many familiar faces here and all of them are incredible and beautiful creatures. Hopefully there are even more insect delights and finds to enjoy in the upcoming year. To ring in the new year, we have the following insects:
Monarch Butterfly - Danaus plexippus - Order Lepidoptera (August 7th)
Green “Goldeneye” Lacewing - Chrysopa oculata - Order Neuroptera (July 26th)
Carolina Locust - Dissosteria carolina - Order Orthoptera (August 20th)
Dog-Day Cicada - Phymata pennsylvanica - Order Hemiptera (August 24th)
Milkweed Beetle - Tetraopes tetrophthalmus - Order Coleoptera (July 9th)
Red-Legged Grasshopper - Melanopus femurrubrum - Order Orthoptera (September 13th)

All pictures here were taken in 2023 with a Google Pixel 4.
Wishing everyone a very Happy New Year and a great 2024! And thank you everyone for making this a wonderful year of insects!

NEUROPTERA MOMENT 2 (Dysochrysa furcata above)
Family Chrysopidae - Green Lacewings
There are about ~1200 species of green lacewings distributed worldwide. The adults of most species are green with golden eyes. They have four venated approximately equal wings!
They have a wingspan ranging 6 to over 65mm (the bigger species are tropical). Lacewings of the Chrysopa genus are sometimes known as "stinkflies" because of their ability to produce a vile smell with a special gland.
Chrysopa nigricornis below
Adults are crepuscular or nocturnal and they feed on pollen and nectar but also aphids and mites, with some species being fully predatory like the lacewings of the Chrysopa genus.
Cool little fact: Adults that feed only on plant substances have special symbiotic bacteria inside some of their trachea that provide them with essential nutrients defficient from their diet.
They are usually found flying near grasses and shrubs and are especially attracted by flowers like cosmos, sunflowers, dandelions etc.
Lacewings have two different modes of hearing.
1. They have a tympanal organ at the base of each forewing which can even sense ultrasonic sounds. When they detect the low ultrasound calls of bats they cease flight and drop and while the bat appraoches, as its call's frequency increases, the lacewings takes it as signal to open it's wings an flap away quickly in an escape manouevre
2. They can also perceive low-frequency vibrations in the ground with special organs located inside their legs. During mating they produce different "courtship tremors" with their abdomen, therefore this type of hearing is important in reproduction. Songs are also species specific!!!
Chrysoperla lucasina (below)
The larvae are… of course… very fierce predators and also called “aphid lions”. They feed on other small insects, especially aphids and caterpillars and they don’t discriminate so they’ll feed on eachother too (thankfully, since their eggs are layed by females on hanging stalks they are out of reach from the hungry grasp of the newborns, so the still unhatched eggs are safe for a while).
A larva:
The larvae have weak senses, so they walk in a weird random manner and sway their heads from side to side hoping to bump into a possible meal, and when they hit anything, they grab it with their maxillae. They inject their prey with digestive enzymes and paralysing venom and can apparently dissolve the organs of aphids in about 90 seconds. Wild. Oh and of course, then they suck yum yum with their hollow maxillae! Afterwards, some use the remnants of their meal (the integuments of aphids mostly) to camouflage themselves and to detter predators!
Below: A larva camouflaging itself by carrying various debris
If they feed continuously for about two weeks they are ready to spin a cuccon in which they sit for about two weeks (some species overwinter however so they can sit inside for longer). Adults are short lived, about 4-6 weeks, but this needs checking.
Nothochrysa californica (below)
Also, green lacewings are often used in pest control!
That's it for now, it's almost 1:30AM something is wrong with me. No time to fact check rn fr
