This hag moth, or monkey slug caterpillar ( Phobetron pithecium) was found on a pawpaw along the Meramec River at Shaw Nature Reserve in early September.
As it seems I say every year, I did not find the time to go out looking for insects as much as I had hoped for in 2020. Here are a few of my favorites from this past season. As always, please correct any inaccurate species identifications if you are in the know. I try my best, but can always be wrong. Thanks.
This punctured tiger beetle ( Cicindelidia punctulata) provided quite a lighting challenge for Casey and me.
We found this crane fly in late April. It makes a nice compliment to the early oak leaf.
I tried capturing this greater bee fly ( Bombylius major) in mid-air, but failed in that attempt. A portrait shot would have to suffice.
This monarch caterpillar was found feasting on the leaves of swamp milkweed that was in a planter near the SNR visitor’s center.
Sarah and I found this hanging thief robberfly ( Diogmites sp.) feeding on a German wasp ( Vespula germanica) on the side of our house in July.
While looking for cats at Weldon Spring CA one evening, I was thrilled to find this saddled prominent ( Heterocampa guttivitta) that had been parasitized by braconid wasps. This particular species of parasitoid changes the chemistry of the host’s brain so that after the was larvae emerge the caterpillar spins its own silk around the developing pupae and stands guard over them. When touched, the caterpillar thrashes and hisses, guarding them until it starves.
One of my favorite cats to find is Apatelodes torrefacta (spotted apatelodes). They can be found in yellow, or this white form. One day I’ll have to track down an adult to photograph.
A White-blotched Heterocampa ( Heterocampa umbrata) shows off its incredible camouflage that allows it to eat as it becomes one with the leaf.
A waved sphinx ( Ceratomia undulosa) that has been parasitized by numerous braconid wasps.
In September, I found this nice specimen of a fungus in the Cordycipitaceae family that had attacked a spider. This is most likely Gibelulla leiopus, an obligate parasitic fungus that preys on spiders with an almost worldwide distribution.
Of course I did a little slug moth caterpillar hunting this season. Here I photographed this crowned-slug ( Isa textula) catterpillar by using the flash behind the leaf, showing the delicate patterns of the insect.
The highly variable stinging rose slug ( Parasa indetermina) is always a welcome find.
The same species pictured above, here showing its bright red underbelly.
I found this spiney oak slug ( Euclea delphinii) by searching the undersides of oak leaves at Babler State Park in mid-September.
The skiff moth ( Prolimacodes badia) cats are highly variable, ranging from nearly a complete uniform green to being more decorated like this individual.
Here is the same individual as above, showing more of its interesting “senescent leaf” patterning.
A very common site while looking for slug moth cats, this Nasan’s slug moth (Natada nasoni) caterpillar has the egg of a tachinid fly on it. Most likely a death sentence for the caterpillar if the egg does hatch and the parasitoid larvae invades its host.
Only my second find of this species, this inverted-y slug ( Apoda y-inversum) was found at Weldon Spring CA in mid-September.
Thanks for the visit and wishing you a great 2021 filled with more insects!
