Eastern bloodsucking conenose vs Masked hunter
These two are easy to mix up. Here's how to tell an eastern bloodsucking conenose from a masked hunter, and whether either one bites or stings.

Eastern bloodsucking conenose
Triatoma sanguisuga

Masked hunter
Reduvius personatus
≠The key differences
Masked hunter (another assassin bug) can be similar in size but does not feed on blood; it preys on insects such as bed bugs, has a shorter, rounder head and lacks the orange abdominal edge markings, though it can bite painfully if handled.

🔍How to spot an eastern bloodsucking conenose
- Elongate, flattened body with a narrow, cone-shaped head and long beak (proboscis) for blood feeding
- Adults about 16-21 mm long, dark brown to black overall with orange to reddish marginal markings on the abdomen visible when wings are folded
- Nocturnal habits and attraction to lights; often hide in cracks, wall voids, under porch steps or in rodent nests
- Winged adults (wings cover most of the abdomen) while nymphs are wingless until the final molt
🔍How to spot a masked hunter
- Adult body length about 17-22 mm with elongated, flattened profile and a narrow neck behind the head
- Long, three-segmented beak (rostrum) held under the head used for piercing prey
- Nymphs often dressed in a conspicuous coating of dust and lint they gather, making them look fuzzy or camouflaged
- Generally dark brown to black adults with long spindly legs; not brightly colored

Identification from photos is never certain: don't handle insects you can't identify, and get medical advice for bites, stings or allergic reactions.
