Heterotoma planicornis is a species of bug from Miridae family. Heterotoma planicornis can reach a length of about 4.6–5.3 millimetres (0.18–0.21 in) in males, while females are quite longer, reaching 4.9–5.5 millimetres (0.19–0.22 in).
The species are black or dark red coloured with pale green legs. Adults have some short hairs and strange shaped antennae, with a large flattened second antennal segment (hence the Latin species name planicornis, meaning flat horn). The nymphs are reddish in color and also have said strange antennae.
These species are look almost like its counterpart, Heterotoma merioptera and can be difficult to distinguish. The eggs are laid into young wood, hatch in May and the nymphs become adults by June. Adults occur from July to September. The eggs overwinter. This plant sucker shows one generation per year.
The nymphs and adults are active predators of spiders, aphids and mites. They are polyphagous, feeding on various insects (Psyllidae species, aphids and small other insects, Chrysomelidae and Lepidoptera eggs), but also on numerous plants and trees.
They prefer unripe fruits, buds, juices and nectar of various plants, mainly... Wikipedia →

Rare
Under 5% of wildlife watchers report a Common Flathorn Plant Bug sighting in Vancouver on a given day, based on 21 verified sightings from GBIF citizen-science data. It is the 208th most-seen of the 482 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 20%, if each day is a fresh chance.
July
In that month about 10% of wildlife watchers report a Common Flathorn Plant Bug in Vancouver on a given day, against under 5% in August to June, the lowest months. That is one of Vancouver's driest months, with about 25 mm of rain against 210 mm in November.
16th of 23
Of the 23 cities where we can rate Common Flathorn Plant Bug sightings, Vancouver ranks 16th at under 5%. The best odds are in Birmingham (United Kingdom, about 10%), Brussels (Belgium, about 10%) and Sacramento (United States, about 10%).
GBIF citizen-science records
It is estimated from how often the Common Flathorn Plant Bug is recorded against all the insects logged in Vancouver (21 verified sightings), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
