Quick ID Burrowing Webworm or Tubeworm Moths

Quick ID
Burrowing Webworm or Tubeworm Moths Acrolophinae

Tubeworm moths of Acrolophus are remarkable for their hairy nose cones (palpi) Males often have very long palpi thrown over their heads like elephant trunks. Females have hairy, shorter nose cones that project outward from the head, not curved. Females are seldom seen.

Four have a lion mane-like thoraxes. The other two have thin, erect hair (spiked). Antennae are bright yellowish-brown. Length 9 to 16 mm. All except one fly from mid-June to the end of July.

 

Very little is known of their life cycle. Most larvae feed on roots and leaves of grasses and clover, building silk-lined tubes in tunnels underground and appearing at night to feed. They over-winter in larvae stage, continue feeding in spring and pupate inside their silk-lined tunnels to emerge as adults in summer. Ontario has 6 species of Acrolophus (2 of them new) and one that could possibly expand it’s range from Ohio into Ontario. One other one, Amydria effrentella is common in Ontario.

Ontario:
Acrolophus arcanella New
Acrolophus morus (mora)
Acrolophus plumifrontella Possible
Acrolophus popeanella
Acrolophus propinqua New
Acrolophus texanella
Amydria effrentella

All Acrolophus species fade quickly. New, freshly emerged species with large manes often have a line or two of iridescent white dashes, a scattering of iridescent white spots, or both.

Explanation of the term ‘triangle pattern’. Inner margin yellowish to white with two yellowish/white triangles and with a dark triangle before and between the yellowish triangles.

Quick ID Acrolophus males

Lion mane thorax:
Acrolophus arcanella – the only one with short, hairy nose cones (palpi), pointed; extend only to top of head, not curved. Triangle pattern. Dark brown-black, fading to light brown. New for Ontario.

Acrolophus popeanella – cream to yellowish diagonal stripe from wing base to inner margin. No triangle pattern. Dark brown or reddish-brown fading to almost entirely yellow. This is the most common species in s. w. Ontario and also has the most extreme colour changes.

Acrolophus plumifrontella – mostly brick red, usually maintains red along outer (costal) margin when old. Overall it appears shorter (smaller) because wings are very wide (6 to 7 mm) and wing tip is straight or squared. In Ohio and expected in Ontario. (No photos).

Acrolophus texanella – dark slanted patch near hind margin close to inner margin, usually with a white slanted line before patch. Long, thickly scaled antenna to mid-wing. Faint triangle pattern. Dark brown fading to light brown.  A smaller species with two found at Point Pelee National Park in 2012, and one in Norfolk (not date). No photos.

Hair spiked thorax:
Acrolophus morus (mora) – Variable. Large with pointed wings. Triangle pattern. Palpi short, reaching to base of thorax. Antenna long, to mid-wing. Legs hairy. Best ID’d by fly date of September to October, long after all other Acrolophus in Ontario. A more northern, rare species; not in s. w. Ontario. (No photos).

Acrolophus propinqua – Entirely brownish-gray with purplish iridescent sparkles; no pattern. Wedge shaped; narrow wing base and wide wing tips. Palpi long, darker on fresh individuals, fading to entirely bright orange-yellow on older individuals. New for Ontario.

Older adults have vestige of the hair bands barely visible. Female abdomen tip has reddish-orange hair, difficult to see because tip is curved down. Male abdomen tip is deeply lobed, with a white tuft on underside.

Size: Female 11 to 13.5 mm.; Male 10 to 12.5 mm.

Habitat: Forests and edges.

Food: Potentilla, Beebalm, Thistle, Alfalfa. Note: In Wheatley, they had a preferences for purple to reddish-purple flowers like Blazingstar, Hyssop, Obedient Plant, Purple Vetch, dark Morning Glory flowers and Lobelia.

Point Pelee Bio-Blitz

At the Moth Light
July 21, 2018

Exciting night at the Point. One of the few times they allow moth lights, and it was a great show. Brock University students drove down from the Niagara area and set up a 400 watt light and a bed sheet. Very simple but effective. Mosquitoes were thick only for the first half hour, after that they left us alone. I managed to get one decent shot of a Snipe fly during the mosquito onslaught. The two photos of Tubeworm Moths show the difference between the dark fresh ones and older pale individuals. The dark one is a bit blurry, sorry.

Here’s what we found.

Elophila tinealis

Black Duckweed Moth
Elophila tinealis

 

DNA problems between BOLD and GenBank (see Comments section below). I do not have Munroe’s original description from 1972. The description is from my observations, and ID is tentative.

POHL: 80-0728
MONA: 4754
GenBank: 691574

Identification:
Head: Black. Nose cone (palpi) black, short, projects and curves slightly upward.
Antenna: Black, short, reaching middle of thorax.
Thorax: Black with varying amounts of silvery scales.
Wings: Black with varying amounts of silvery scales. Silvery-white blotch usually present at mid-wing, but not always. Wing tip border has row of uneven white dots and/or dashes. Fringe two-tone, gray with darker tips. Female wings are longer, extending well past abdomen tip; male wings just past abdomen tip. Hindwings brown-black, fringe twice as long.
Legs: Black with varying amounts of silvery-white pile.
Abdomen: Black, lower margin of segments may or may not have light brown to whitish lines. Female abdomen wider than male.

Size: 4 to 6  mm long. Wingspan 10 mm.

Habitat: Marshes, ponds, still waters.

Food: Duckweeds Lemna and Spirodela

Flight Time: June to early August

Life Cycle: Mating occurs within 24 hours after emerging. Females lay eggs within an hour after mating, laying eggs singly to 10 at a time on the lower surface of Duckweed. Eggs hatch within a week. Larvae stay on underside of leaf and construct a case. Live and pupate in the case. Life cycle complete in 24 days. Adults lived only 4 to 5 days in lab.
Larvae 8 to 9 mm long, white to brownish-yellow; back of head black. Shield has semi-circle of brown spots.

Comments: Central and southern Ontario.
DNA: All samples submitted to GenBank from Point Pelee were ‘suppressed’.
All samples from Thousand Islands National Park and 8 of 11 from rare Charitable Reserve near Cambridge have a GenBank reference number, but clicking the link to GenBank returns a ‘Not found’ error.
The DNA of 3 samples has been accepted by GenBank from rare Charitable Reserve, plus 1 from Pt. Franks, Lambton County, and 2 from Wellington County. No photos on BOLD of the accepted samples from Charitable Reserve. The photo from Pt. Franks look different, wings narrower and lacking the white dot-dash line around wing tip; center white spot is very sharp and well-defined, unlike other tentative E. tinealis. Photos of the 2 from Wellington County are too poor for analysis.

Female: Segment 1 gray, segments 2 to 6 black with sides and lower margin white. Underside brownish. Ovipositor black, considered short, cone-shaped.

Similar Species: Both the male and female Efferia aestuans have an obvious pair of black stripes on thorax and bright yellow toes (foot pads or pulvilli). Male has 3 white segments (not 2) near abdomen tip. Female has very long, thin ovipositor (not cone-shaped).

Size: 16 to 19 mm.

Habitat: Prefers sandy beaches with dune grass. Sandy meadows near forest edge. In Ontario, only found along Lake Erie and Huron shoreline and inland.

Food: Grasshoppers, Flies and Wasps. Will also eat other Robber Flies.

Flight Time: June and July

Life Cycle: Females lay eggs (about 20) in sand. Larvae food is unknown, but have been found in soils infested with white grubs. Pupate in late May and emerge as adults in June and July. Adults frequently found flattened and quiet, blending in with the warm sand in cooler weather. Prey usually captured in mid-air. Males tackle females for mating in mid-air and then drop to the ground.

Comments: Essex County – Point Pelee National Park; Kent County – Rondeau Provincial Park; Lambton County.
