Description
 
 

Snowberry clearwing is a common, colorful, small to medium-sized, day-flying sphinx moth. It has a wingspan of 1¼ to 2. It is highly variable in appearance across its range. Fifteen forms have been described.

When the adult first emerges from the cocoon the wings are completely covered with reddish-brown scales. The scales begin to drop off with the first flight, eventually leaving the wings clear except on the margins and along the veins. The forewing is long and narrow with a smooth, slightly convex outer margin. It is mostly transparent except at the base; a thin terminal margin with a usually smooth inner edge; an orange apical spot; an orange stripe along the inner margin; and dark scales outlining each vein making them appear bold. The forewing cell is boldly outlined and undivided. The hindwing is mostly transparent except at the base, a thin terminal margin, and bold veins.

The thorax is golden-yellow on the sides blending to olive-brown or olive-green with a brown dorsal stripe above. The abdomen is mostly blackish. The first 3 abdominal segments are black. On some freshly emerged individuals there are some blue hairs on the first abdominal segment. The fourth and fifth abdominal segments are yellow above and on the sides and black below, forming a broken band. Tufts of long hairs flare outward from the last abdominal segment and look like feathers. There is often with a patch of golden-yellow to golden-brown hairs in the middle.

The head is olive-green or olive-brown above, golden-yellow below. There is a black stripe through the eyes that continues diagonally across the thorax. The antennae are black, thickened, and club-like. The proboscis is long and is coiled under the head when not in use.

The legs are black.

The caterpillar is up to 1¾ long. It is usually bluish-green above and yellowish-green on the sides. Sometimes it is entirely brown. The head, thorax, and abdomen are moderately covered with prominent, minute, white bumps (granules). The head is green. The leading edge of the thorax has a yellow collar covered with prominent yellow granules. A long, curved horn extends from the eighth abdominal segment. The horn is yellow at the base, black from the middle to the tip. The spiracles are outlined with a black spot within a white spot. There is a minute white dot within the black spot above and below each spiracle. The leg-like structures (prolegs) are yellowish-green at the base, black in the middle, and dark brown at the end. Mature caterpillars can be found from June onward.

Behavior

 
 

Adults fly during the day. They are not attracted to light.

They do not land on a flower but hover next to it while feeding. Sometimes they extend their forelegs into the flower, possibly to taste it.

 
     
 

Life Cycle

 
 

Females attract males by releasing pheromones. After mating, she lays spherical green eggs on the underside of host leaves. The eggs hatch in about one week and the caterpillars begin feeding on leaves and fruit of the host plant. They molt five times in four weeks before pupating. The first generation pupates in a cocoon among the leaf litter on the ground. Adults emerge two to four weeks later. The second generation caterpillar burrows into the soil and overwinters as a pupa and emerges in as an adult in May or June.

About

H. diffinis (Snowberry Clearwing) has black legs, the legs of H. thysbe (Hummingbird Clearwing) are off white to reddish, H. gracilis (Slender Clearwing) does have more maroon colored legs than H. thysbe, but the best character to diagnose H. gracilis is a reddish-brown patch along the side of the thorax where the legs meet the thorax, that coloration carries over into the legs. - Ryan St Laurent on Mothing

Saw at least 4 of them in a small field with flowering weeds within the First Chain Lake area of Halifax, Nova Scotia. Didn't seem to mind my presense as they were practically flying into the camera.
