Collecting Clogmia albipunctata

Collecting Clogmia albipunctata, commonly known as the drain fly, filter fly, or moth fly, follows a different approach compared to hover flies like Pelecinobaccha sp. These small, fuzzy flies (Psychodidae family) thrive in moist, organic-rich environments, and their collection requires targeting their specific habitats and behaviors. Here’s a general guide:

1. Understand the Species and Habitat

• Clogmia albipunctata is a tiny fly (about 2–5 mm long) with hairy, moth-like wings and a distinctive spotted pattern (white spots on dark wings). They’re weak fliers and often hop or flutter short distances.
• Adults are found in damp, dark places rich in decaying organic matter, such as:
• Drains (sinks, showers, toilets)
• Sewage systems or septic tanks
• Wet basements, bathrooms, or kitchens
• Outdoors near stagnant water, compost, or rotting vegetation
• Larvae live in the gelatinous biofilm lining drains or moist organic debris, feeding on bacteria and fungi.

2. Timing

• Clogmia albipunctata is active year-round indoors, especially in warm, humid conditions (above 50°F or 10°C). Outdoors, they’re more common in warmer months (spring to fall in temperate climates).
• They’re most active at night or in low-light conditions, resting on walls or surfaces during the day. February 20, 2025, suggests indoor collection is viable now in heated spaces, while outdoor collection depends on your climate.

To collect Clogmia albipunctata effectively, focus on moist, organic-rich spots like drains or damp corners, using an aspirator or small net for adults and targeting larvae in biofilms if needed. They’re easy to find in the right conditions, so patience and precision are key. Let me know if you’d like more specifics or help identifying them!
